No, no, a thousand times NO.
As much as the account farming spammer population drives me batty, instituting a KYC policy would be so much worse and would be against what much of bitcoin stands for. There are ways to combat spam that have yet to be implemented--like tougher rules for bounty managers and project developers and so forth--and this forum does not need people's dox.
TL;DR Fuck that.
It certainly doesn't have to be a full KYC audit. I mean it is not like we have to comply with any governmental regulations. Just something to let the forum know you are who you say you are.
I do like your ideas for tougher rules on bounty managers and project developers. You see, like reasonable men we are already finding common ground!
