Just going to respond to the point regarding me.
Here is where you are wrong. theymos built the merit system so that "merit abuse" does not matter as one merit received equals roughly 0.97 merit that can be sent to sock puppets. The merit system will be unaffected by "abusers" as long as no merit source is involved. User actmyname is controversial enough, and has a low enough accuracy is his ratings that theymos excluded actmyname from his trust list:

Gotta love coming back to this. There may have been a disagreement between theymos and I regarding the merit farming tags (to which I changed some ratings) but it's a matter of perspective. Stating that any merit abuse would be a 'rounding error' is true but allowing it to pass shouldn't happen on principle, in my opinion. Might be a slippery slope fallacy, but I don't think it's good to allow that kind of scummy behavior since it begins to build the foundation of false thinking, leading to recursive scumminess.-thermos sealed-
actmyname doesn't run any signature campaigns, but does Red Tag many users who "abuse bounty campaigns" and who trade forum accounts.
Should I start? 
The account farmers I've been tagging are more current-age than in the past. In terms of tagging the users that abuse bounty campaigns, it's simply breaking the rules. Users have no excuse. In regards to account trading, I believe that it is common knowledge (or with a little bit of thinking) that the act results in either scams (from the actual trade or post-trade via the account) or participation in a signature campaign. The former is obviously bad so we don't need to discuss this.
