As your account ages there will be more information about whether you are real or not. Stopping the influx of bots before they do damage is important. Therefore it’s quite likely that Twitter ban accounts early if they look like bots based on not much info (and potentially if they look low value).

You followed a few people who are popular account (not friends, fairly anonymous) but not mainstream accounts (so you’re a little more atypical) and then you post once with, sorry to say it, not particularly inspired/original/specific/human content. Perhaps there were other factors. I’d guess you didn’t go through and fill out your profile much if you weren’t that invested in the idea? No birthday or avatar maybe? Not following the easy setup steps that Twitter encourage you to do?

Combine this looking a little like a bot with the likelihood that you’re going to be low value because you’re not that engaged (debatable I know), and it kinda makes sense.

All speculation, but a possibility. Should Twitter be doing this? I don’t think it’s the worst thing, but it’s a trade off. If this is it then it would imply that your marketing efforts for your game would probably not be affected at all.
