After ignoring the wiki ( http://wiki.lutris.net/ ) for a long time, we had with a severe spam problem.
The antispam protection that was in place must have been disabled by a MediaWiki update and we ended up having half a million bot users, even more spammy pages and received a DMCA takedown notice from the Red Cross.
There was very little content on the wiki and a lot of it was outdated so I decided to burn everything down and restart from scratch.
The wiki container has been updated to Ubuntu 16.04, PHP was updated to 7.0 and the entire database was cleared and rebuild by the MediaWiki installer.
Anonymous edits are disabled (they were disabled before as well) but more importantly, account creation is disabled as well.
I want to make this wiki an official documentation for Lutris so I figured it made sense to restrict edit access to known contributors.
If you wish to get edit rights to the wiki, send me an username and your email address and I will sign you up.
