Compare the last tweet before your previous expulsion and this one. Any similarities?
Your most recent tweet could possibly be picked up by the new spam filters they built to try to battle the cryptocurrency bots: "Impressive. That's significantly more ETH than I got in a year for the newsletter, and that was when ETH was worth $10"
maybe, but another similarity was that I was outside of the US both times. so who knows?
the bottom line is that Twitter is terrible. They can't write an algorithm that will suspend accounts that are obviously scamming, yet they frequently suspend people for no good reason and take a long time to unsuspend their account.
