i'm actually disapointed to see that feature here.
it looks good on paper, but in practise is easy abused and quickly rendered pointless.
one case study: gun forum i frequent has it.
one dude just found firearms last year or so. does'nt know his elbow from his asshole about them. yet posts pics of scantily clad females at every chance. as a result has the highest rep point count on the forum.....for PA firearms owners....
