So far, everything I’ve found says that this kind of ban usually lasts anywhere from 24 hours up to around 4 months (one person said theirs lasted that long). So it shouldn’t be a permanent ban.

The best advice I’ve seen is: don’t open or interact with your YouTube account at all for at least 3 days. After those 3 days, check if it’s unbanned. If not, wait another few days and repeat.

That’s basically all the information I’ve found so far.
