Two of my Twitter accounts got suspended.
I did an appeal, contacted Twitter support.
They sent this message:
Hello,

We typically suspend accounts for violations of the Twitter Rules (https://twitter.com/rules) or Terms of Service (https://twitter.com/tos). Additionally, repeat violations may result in permanent account suspension.
Thanks,

If you did not do anything wrong / against their TOS then you should be fine. Just wait.
