Lets talk about the more recent examples that have cropped up on other forums. One person was banned for fishing for too long while finishing an ebisu +1. Another person was banned and they're not sure why but at their best guess it was from being in the same skirmish run as someone who was flee hacking. If you're going to get STF banned for playing the game for too long or being in a party with a cheater that is concerning. I'm all in favor of banning people blatantly abusing game mechanics but these examples are not those kinds of players.
This is why I've deactivated my subscription. I knew some of those people and they aren't the type to lie about this stuff. They honestly were not using TPP or violating the ToS but somehow got caught into SE's automatic YOUR-BANNED lottery. I'm honestly beginning to think it's a random lottery, like if the STF doesn't make their monthly metrics for required banned accounts they just randomly add some NA accounts onto the pile to meet quota. Wouldn't surprise me considering job performance is often tied to such reportable metrics. In any case the STF should NOT be handling this unless they have a customer facing entity. Both the customer support and In Game team (GM) have customer facing elements, though Customer Support should be able to conference in a GM during a support call to prevent the catch-22 of needing to contact the in game team while being suspended.

The STF needs a customer representative to talk with players and offer some insight along with a process for reinstatement if the suspension was possibly in error. They are human, they make mistakes like everyone else but right now nobody is fixing or dealing with those mistakes.
