Who else is sick of all these damn lurkers and leachers? (Rant)

No seriously, This is ridiculous. It's on every single post everywhere. Some fresh account coping and pasting the same comment to get points. And what frustrates me even more is that the staff can't do much about it because there's so many of these accounts. Staff can't catch them all! I wish there was some kind of way this can be prevented because it simply not productive.
