Can I be banned because of that?

I insulted someone at the party because they insulted me, he said he clipped it and sent the support, can I be banned because of that? If so, how long?

Don't think he picked it up. That will have been an empty threat. But if it does, that depends on the insult. A few days of ban are possible in this case.

If he really took it in. Then you can already be banned

Is there a perma for that?

I do not think so.
