Haven't tested lately, but at least for a while you could get your account blocked by publicly suggesting people follow you some other place.

PG got suspended for directing his followers to Mastodon: https://x.com/alexisohanian/status/1604604968677392386

They did walk that policy back due to the backlash, but they really wanted to do it.

I made my account private and put my bsky address in my profile, so that doesn't appear to be an insta ban.

IIRC, it was for a while and then the decision was reverted.

It received so much backlash it didn’t even last one day.

No, I described a way of getting blocked that I personally enjoyed. Haters (me) gonna hate, after all.

I think the FSF should not be on Twitter at all. Sorry if I was unclear about that in my previous comment, but the first paragraph was meant to contradict OP's suggestion.

could change birthday to underage and get banned that way
