I won't lie, sometimes I have considered defending someone who was being namedropped, logged in or not. Only 2 things stopped me from doing it:

1- The complains were actually things I had seen myself, which made defending them quite hard when I agreed with the complains even if not the tone.
2- This is the hate meme, only time I would consider posting something positive about someone here (specially someone who was being criticized) would be on opposite day.

So clearly that person is an idiot.
