Now that there is the three likes rule in place I suppose it takes away the possibility of hit and run spamming. It now takes a lot longer to start silly and unhelpful threads. I have noticed Digital Point is becoming better at responding to posts reported by users too.
The problem with the 3-likes system is that there is a zero incentive to contribute once the threshold has been passed. Also, I can't help wonder, how long will there be until a service selling likes will pop up on BHW?
the 3 likes rule is good i think for cutting out most of the newly registered spammers though as IG2010 suggested, probably soon you will see someone selling likes on fiverr btw, i am new here.. since when you guys put this rule in effect?
