the problem with that is, if someone doesn't want to leave a comment, they can just write random shit likt "kljklajwlkjdklclkbn d,mnlekrjlq".....the system wouldn't be able to tell teh difference, and were back to square one.

Perhaps if all rep points given first had to be approved by mods/admins? that way, people wouldn't be able to give bad rep for no reason, and they'd have to write some sort of comment each time. It would also make the rep system better since people could no longer hand out rep just for the hell of it
