Well, I thought I'd help out with spreading word about art thieves. :3 Tell me if you find any!
And please, if you meet up with any of these thieves, just report them. No need to give them attention, if that's all they want. Also, if they're harassing you, there's a block option for a reason. ^_^
Now, heres a little guide for when you're browsing through this...
When you're looking at the titles, these are some things you might see and what they mean.
Message in "": The situation is completely dealt with.
Message in "()": The situation has stopped, but it hasn't been confirmed that it's stopped for good.
No message: Still stealing.
Now, it's kind of hard to keep up everything with all these thieves, but I'll try to keep updated as much as I can with each situation. ^^'
