guest364116 needs to be stopped

I couldn't find a way to report users from the profile page so I hope this is the place to do it. I apoligize for putting it in "bugs" but I don't know which section would be more appropriate.

Guest364116 has been posting non stop spam on a lot of images. I've reported a lot of the images and they've been removed but I think the entire user needs to be removed, if that is possible.
