Apologies. It seems certain files in Special:UnusedFiles are actually in use - my bot just goes through the process of deleting all images listed in that page. I'll be aware next time before running the bot's sequence again.
In the meantime; I'll be restoring any images that actually link to pages (whether or not they're listed in the UnusedFiles page) - feel free to restore any that need to be as well!
On the Stuffz Wiki the creator of the Wiki (Ghosto (now Weegeelover))'s sister hacked his old account that he created the Wiki with called Ghosto and now he moc=ved to Weegeelover but now his sister is constantly hacking his old account and we can't get rid of her since she's a Burrecat or whatever and she made another blocked user a burrecat. I think the only way to get rid of her is for me to adopt the Wiki because if Weegeelover get's it then his sister can simply hack that account and it will start all over again. If you want proof go check out the Wiki. And if you do then please make Abcilikepie, Ghosto, and Secretwikiagent not burrecats so they can't unban themselves?
You are free to re-upload these for any purpose as they are in the public domain. They shouldn't need to be resized either — 19 x 19 is about the size they should be, so they should fit as icons as they are.
