I certainly don't perform "astro-turfing"
that's exactly what an astro-turfer would say!

i usually left the discussion when the troll start going off-topic, insulting other member (where as few others decide to respond with insult) or bring another point which i already discussed previously.
And if i want to do "astro-turfing", i could do it by correcting every single statement which made by people who don't know about technical topics at all which is far easier.
indeed, you contribute all over the forum. one could make the argument that I am a former astro-turfer/troll-bukkaker covering my tracks, as I used to engage trolls too much, if only to identify them as such
@WindFURY and @DooMAD exist seemingly only to talk to the trolls though. They barely make any other posts.
you're just figuring that out.
