I was one of the main culprits tagging shitposters before the merit system was implemented.  It was never a good use of the trust system, and I knew that at the time--but the situation was so out of control that I felt I had to use the tools at my disposal, and the trust system was pretty much the only one I (and actmyname) had.  I haven't negged a shitposter since then, and I've removed all the negs I'd left.  Not sure why you're bitter now, because spammers/shitposters aren't getting tagged that I know of.

Eh, that's one solution but I respect people who complain about things as long as those complaints are at least semi-reasonable.  If nobody complained, there would be no progress and there would be a lot of bottled-up anger. 

That was a good move on Theymos's part to get rid of that field.  I think it got abused more so than used properly.  That information can be written right in the feedback itself.
