"There MUST BE cheater sympathizer in all of those"? REALLY? That is the only possible explanation? It could not be that the claim that a given player was cheating was not adequately backed up by facts?
What's the point of your post? What I read is "I report cheaters and nobody does anything about them, so that proves there is some great consipiracy afoot". 'Scuse me a minute while I put on my tinfoil hat.
Rather than bitching that the unpaid volunteers doing the 3rd party anti-cheat service that DICE refuses to do are not doing it the way you would prefer, maybe just say "THANKS FOR TRYING".
As for your argument that a PB ban means the player is cheating... ABSOLUTELY FALSE. One guy in my community 5+ years ago was a server admin and he was banned by PB while spectating a game on his work PC. PB listened to his appeal and said "you're a dirty dirty cheater" and left him to rot. It was something like 9 months later when Evenbalance posted the standard "we have discovered ban #12345 could be issued in error" notice and PBBans and friends removed his ban. By then he'd been ostracized from our community, gotten a new userid, and moved on to play with others since we wouldn't let him play with his new id. That event has stuck with me. And now PB is even worse.
Punkbuster went rogue over a year ago. It was like a switch flipped, and they started issuing bans to a whole lot of innocent people. And it happened about the time they seemed to switch from doing bans "the old" way, where a given ban code was attached to a given cheat, to doing more "stealth" bans, where they'd just kinda watch for week and then lump many new bans together into one catch-all. They stated they did this to make it harder for cheat authors. But they also started issuing a whale of a lot more lifetime GUID bans, which render an Origin account useless for BF4 for life. They almost never did that, prior. And now between those, a whole lot of innocent players have been screwed.
A whole lot of servers have stopped enforcing PB bans. GGC-Stream.net(kinda PBBans "competitor') stopped putting new PB bans into their DB a long time ago and now only put in new bans for sullied screen shots and MD5 failures (I think), while continuing to ban for the old Punkbuster catches. They effectively threw in the towel, admitting Punkbuster is now unusable.
So, yeah, I don't think too much of your conspiracy theory.
