If you only read the DCCWiki project website, no more information is collected than is typically collected in server logs by web sites in general.
If you contribute to the DCCWiki project, you are publishing every word you post publicly. If you write something, assume that it will be retained forever. This includes articles, user pages, and talk pages. Some limited exceptions are described below.
Publishing on the wiki and public data
Simply visiting the web site does not expose your identity publicly (but see private logging below).
When you edit any page in the wiki, you are publishing a document. This is a public act, and you are identified publicly with that edit as its author.
When you publish a page in the wiki, you may be logged in or not.
If you are logged in, you will be identified by your user name. This may be your real name if you so choose, or you may choose to publish under a pseudonym, whatever user name you selected when you created your account.
If you have not logged in, you will be identified by your network IP address. This is a series of four numbers which identifies the internet address from which you are contacting the wiki. Depending on your connection, this number may be traceable only to a large internet service provider, or specifically to your school, place of business, or home. It may be possible that the origin of this IP address could be used in conjunction with any interests you express implicitly or explicitly by editing articles to identify you even by private individuals.
It may be either difficult or easy for a motivated individual to connect your network IP address with your real-life identity. Therefore if you are very concerned about privacy, you may wish to log in and publish under a pseudonym. When using a pseudonym, your IP address will not be available to the public, but it will be stored on the wiki servers for a relatively short amount of time. Thus it will be available to developers and may be released under certain circumstances (see below).
If you use a company mail server from home or telecommute and use a DSL or cable internet connection, it is likely to be very easy for your employer to identify your IP address and find all of your IP based DCCWiki project contributions. Using a user name is a better way of preserving your privacy in this situation. However, remember to disconnect yourself after using a pseudonym to avoid allowing others to use your identity.
The wiki will set a temporary session cookie (PHPSESSID) whenever you visit the site. If you do not intend to ever log in, you may deny this cookie, but you cannot log in without it. It will be deleted when you close your browser session.
More cookies may be set when you log in, to avoid typing in your user name (or optionally password) on your next visit. These last up to 30 days. You may clear these cookies after use if you are using a public machine and don't wish to expose your username to future users of the machine. (If so, clear the browser cache as well.)
Many aspects of the DCCWiki project community interactions depend on the reputation and respect that is built up through a history of valued contributions. User passwords are the only guarantee of the integrity of a user's edit history. All users are encouraged to select strong passwords and to never share them. No one shall knowingly expose the password of another user to public release either directly or indirectly.
Every time you visit a web page, you send a lot of information to the web server. Most web servers routinely maintain access logs with a portion of this information, which can be used to get an overall picture of what pages are popular, what other sites link to this one, and what web browsers people are using. It is not the intention of the DCCWiki project to use this information to keep track of legitimate users.
These logs are used to produce the trending information to determine if or when a new servers is needed to handle current and predicted future loads; the raw log data is not made public, and is normally discarded after about two weeks.
Here's a sample of what's logged for one page view:
22.214.171.124 - - [30/Oct/2005:02:03:19 +0000] "GET /Introduction_to_DCC HTTP/1.1" 200 18084 "http://www.dccwiki.com/Main_Page" "Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-us) AppleWebKit/85.7 (KHTML, like Gecko) Safari/85.5"
Log data may be examined by developers in the course of solving technical problems, in tracking down badly-behaved web spiders that overwhelm the site, or very rarely to correlate usernames and network addresses of edits in investigating abuse of the DCCWiki.
Policy on release of data derived from page logs
It is the policy of DCCWiki that personally identifiable data collected in the server logs will not be released by the developers who have access to it, except as follows:
- In response to a valid subpoena or other compulsory request from law enforcement
- With permission of the affected user
- To Mitch Schwenk, his legal counsel, or his designee, when necessary for investigation of abuse complaints.
- Where the information pertains to page views generated by a spider or bot and its dissemination is necessary to illustrate or resolve technical issues.
- Where the user has been vandalizing articles or persistently behaving in a disruptive way, data may be released to assist in the targeting of IP blocks, or to assist in the formulation of a complaint to relevant Internet Service Providers
- Where it is reasonably necessary to protect the rights, property or safety of the DCCWiki, its users or the public.
DCCWiki policy does not permit public distribution of such information under any circumstances, except as described above. DCCWiki does not sell, rent, lease, or give out information to third parties except as listed above.
Sharing information with third parties
Except where otherwise specified, all text added to DCCWiki project is available for reuse under the terms of the CC-SA 3.0.
DCCWiki will not sell or share private information, such as email addresses, with third parties, unless you agree to release this information, or it is required by law to release the information.
Security of information
DCCWiki makes no guarantee against unauthorized access to any information you provide. This information will be available to all developers with access to the servers.
You may provide your e-mail address in your Preferences. This allows other logged-in users may send email to you through the DCCwiki (unless you disable this in your preferences). Your address will not be revealed to them unless you respond, or possibly if the email bounces. The email address may be used by the DCCWiki to communicate with users on a wider scale.
If you do not provide an email address, you will not be able to reset your password if you forget it. However, you may contact one of DCCWiki developer to enter a new mail address in your preferences.
You can remove your email address from your preferences at any time to prevent it being used.
Removal of user accounts
Once created, user accounts can not be removed. It's not possible for a developer to change the username on an account. See DCCWiki:Right to vanish for further details.
Deletion of content
Deleting text from DCCWiki project does not really delete them. In normal articles, anyone can look at a previous version and see what was there. If an article is "deleted", any sysop/administrator, meaning almost anyone trusted not to abuse the deletion capability, can see what was deleted. Only a developer can permanently delete information from the DCCWiki project and there is no guarantee this will happen except in response to legal action.
