We would never do the Voodoo doll trophy, mostly because it either celebrates mistakes, or celebrates people making false accusations, neither of which are a good thing. Also, you wouldn't believe the number of funky reports we get.
I will admit though, I had a difficult time adjusting to this format, and dished out quite a few warnings to "the person above" due to the way the buttons are laid out.
Any trophy that encourages people to cause trouble, be in trouble, abuse the system, or just do something so trivially easy that anyone can do it aren't something we want to add . . . especially not if it can't be automated.
The vast, vast majority of the trophies given out on the website are completely run by the system, and if we have to do things like regulate posting history, or manually tag people for posting in a thread . . . its just never going to work.
