I guess this is right, but it's also in his/her interest to neg-rep as many accounts as possible, in order to increase demand for farmed accounts. In my opinion, account-farming and default trust are in a clear conflict of interest.
That is a point. I dont think that the amount of time QS invests in haunting (not a typo) scammers is worth the coins earned through sales to said scammers.

Every spammer banned is a possible future customer. The new account will probably get banned as well, because the do not learn the lesson or dont care because they still ROI.
I personally think its part of beeing human to contradict itself.
