Support rarely takes action without some evidence of wrongdoing. So I am dubious of the "I did nothing wrong" claims I see here.
My experience with Support has been that they investigate shallow issues well. Deep issues are another matter, and they do it in a vacuum. I think the biggest problem I have seen is that they mostly listen to accusers, and there is a presumption of guilt. They tend to investigate, judge, suspend/ban, then notify. And once you're there, few appeals will prevail. I have complained to them about the "kangaroo court" nature of their process. There needs to be an escalation/appeal process (they have that in Stripchat). They also need to improve their response times, like A LOT! I get some initial human responses weeks later - for something like a rules clarification question. I'm waiting on one now. I've suggested that they should have paid, tiered levels of Premium support - with guaranteed SLAs - like they do in other major corporations. I'm pretty sure all my suggestions go straight to the circular file.
But to be fair, sometimes they do reverse. I was recently suspended for a response I gave to a troll who asked for my email address. I sent him his own username with @gmail.com on the end and told him to go for it. I was suspended - presumably for doxxing - but they did reverse it within hours after I emailed.
They are not great for explaining the rationale for all their actions, but you might start by asking for that rather than just proclaiming your "I did nothing wrong."
