QS used to be OK but hes becoming increasingly frustrated & seems irritated about the way the forum is run.
I dont know what his problem is but the personal attacks on individuals isnt good practise.
Hopefully he comes to his senses & starts to contribute in a more positive way, everything about him oozes bitterness & negativity at the moment.
I believe that he wants to be the one responsible for bringing down another trusted member. Just like he went from hero to zero, I'm sure he'd relish someone else going from hero to zero.
Furthermore, in this particular case, I suspect QS finds suchmoon's efforts as a threat. If he is still running an account farm, suchmoon's efforts must be frustrating his efforts to rank up his accounts. I am sure suchmoon is reporting much more infractions besides plagiarism. Although posting low quality and off topic posts won't get an account immediately banned, it may lead to that eventually. Also, having posts deleted by the staff can definitely effect revenue, if any alt accounts are enrolled in signature campaigns.
