what should i do?

Stop using reddit

If you rotate your IP, cleaned your session cookies, and don't start again spamming anything, I believe it's highly unlikely you will get automatically flagged again.

But honestly... As others have said, why even bother? Or worst... Why would you worry about it? If you create an account and get banned again while behaving normally, just take it as a lesson that Reddit sucks and move on.

You really that desperate to interact with bots and have your comments scraped to train LLMs?

Been there, done much of that. Welcome to Lemmy.

Time to move on from Reddit

Lol this is not the reddit support channel.
