Before I go any further, let me explain myself. Yes, I did previously state that I would not be returning to this wiki. Call me a hypocrite; I really couldn't care less. The main reason I am posting this is because this is something that is happening on wikis quite similar to this one, as I explain below.
As you are likely well aware, we have recently been dealing with a ton of vandals on this wiki, & affiliated wikis, such as Tal's wiki, the roleplay wiki, the squid wiki, & several others. As I've been going through some of the stuff that the vandals have done, I'm sensing a pattern with these vandals.
They move the content of an article to the page of a non-existing, & quite irrelevant user.
They then remove all content from the page, or replace it with something unrelated or pornographic.
This proceeds to make people lose hope, & feel screwed over.
However, I have gone through restoring several pages on several wikis, & I would like to address how to do this, so that you can restore nearly any page on your own.
Click on the link of the page you suspect has been vandalized. It will likely redirect to a 'user' page. If it instead is just a redirect link, click that as well.
Once you are on the faulty user page, hit the short little downward facing arrowhead next to the edit bar, & select 'History'.
Use the compare feature to compare the current version of this page, to the last edit that was made before the edit saying that the content was moved to this user page.
Once you have loaded the comparison, select the edit button that is a little ways above the non vandalized version, & copy it to your clipboard (Control + C).
From the faulty user page, there should be a link of the page that redirects to this user page. The link should be the original location of the page prior to vandalization. Remove the redirect link on the proper location, & paste (Control + V) the non-vandalized page into the text editor.
I hope that this has been informative, & should help you if you ever come across this issue. After you restore a page, you should immediately report the vandal to an admin.
If you have any further questions, please post on this forum thread.
