Never mind, figured it out. The history was still associated with the new spam name, so have restored it now. If any you guys wanna help, there's a big vandalism flood currently going on at Metal Gear Wiki. Reported IPs to VSTF but he just uses other ones after being blocked.

I took care of the problem for now, though just for future references to make things easier on you, you can easier reach the VSTF for assistance via our IRC channel. If you start your report with !vstf and then a link to the vandal, we are alerted of it immediately and can respond more quickly.

I'll keep that in mind, thanks for your help.

No problem, that's what we're here for. Don't hesitate to shoot us a message if this would start up again :-)
