Banning them for that seems aggressive (vs: blocking/removing that tweet), but it's at least consistent.
Banning all links to any Mastodon server is pretty indefensible, though.
In other cases, twitter accounts were only suspended temporarily, and given that there was nothing about that in the TOS, and Musk updated it post-facto says that they should have never been banned in the first place, the tweets should have been deleted, and that's it.
