I know what I know about my datacenter and many times have I even agreed that there are cheaters even on my datacenter and very likely on every other western one.
EDIT: It is "easy" for me to say not only because I'm just as connected to pvp communities as you, but also because I have practical experience having played with and against them.
Im not pretending they don't exist, neither am I pretending the methods used don't exist.
However unlike you, I don't look for the monster in every shadow. I am not the one with the delusional take claiming that top 100 feast players all or at least 95% you mentioned later gamed and cheated the system somehow. If you make such a ridiculous claim based on the things you've heard and seem to trust, then the burden of proof is on you to prove it with concrete evidence.
Again, I agree with cheaters existing, that is undisputed. I do not agree with straight up defamation of a whole subsection of the PvP community who may very well just have a lot of good players based on theory and knowledge of a tool existing.
If we find anything about new ones, we will talk about them when it comes to it. To ostracise top 100 players and challengers as a whole out of uncertainty and what-ifs is insulting at best and downright unhealthy for fostering a better playbase at worst.
