So there are some famous game griefer on NA server
one is lordsheen which we all know….
the other one is tantantankgod-001 and he also has bunch of alts ending with -002 to -006.
And another one called Biteme_2019, he will sit at the red line and spam "Negative', then drive straight to enemy at 10 min mark.
If you play NA server regularly you will know these famous game ruiners. As far as I know none of them are actually "bot", yeah they decided to grief the game "manually", more amazing thing is that lordsheen actually have a twitch channel and owns a T95/Chieftain, which according to Wargaming, is a "reward for good players!"
I reported them many times but nothing happened, guess WG really don't care NA servers at all.
