No, but you should check, the history on tag and rating to see who had done it. Sometimes it's done by evil trolls. And other times by mods. In the latter it should be commented just to srr what it should be. If you could, could you link me some of the "safe" ---> "questionable" images?

Edit: I believe it may be appropiate to add the pantaloons tag as it seems It has a more extended imagebase then tags like overalls Im sure bakaneko would be glad to maintain the tag. And I would help bakaneko maintain it as well.
