TJKD1994 got a reaction from miminio in Atlantiss confirmed they used some server-side anti-cheat method
Link: https://atlantiss.eu/news/321/the-future-of-netherwing They also announsed perm x2 xp rate (1-70) and "paid" x3 rate (1-58). Transfer from LH etc.
So this comfirms the Bambo's and other people's suspect on how they detact bot. Now the question is can we do anything to it?
