It could be argued that the reason for the ban is not false. Maybe it originated from a complaint from Bitmex...
I don't really fault them because ultimately Twitter is the one at fault here, being the judge, jury and executioner.
So Twitter may have shut down your account because Bitmex asked them to.

Depending on what's actually happened it could be the case that Twitter are legally required to act. I don't think it's entirely fair to blame them until you know more about what's going on.
Now, suppose it actually was Bitmex that requested the accidental take down, it still doesn't help me in anyway since I have no way to contact Twitter. Bitmex has a customer support that responds to emails and my experiences with Bitmex has been quite jovial since the start. In fact, Ben (one of the co-founders of Bitmex) has commented/reviewed some earlier versions of bitmexrekt code many years ago when I had some questions about the API.
Ultimately, the only way to get any support from Twitter is to make big scene on social media, and I really don't want to do this.
Then I'd suggest you look for something new to do, because nothing except that will raise their attention to a level where they might investigate.
