I actually never realised tags are editable by everyone!

I agree, user-submitted tags should be, at the very least, easily identifiable from those added by the author.

They won't fix it, weasyl is as bad as FA these days.
First they screw the site up with the new thumbnails and now the troll tagging feature, going on the thumbs and the fact they haven't even attempted to fix them means the new tagging system is here to stay.

I think the staff are going out of their way to anger people.
