Probably not, as that’s one of the first things they do.

That said, I feel like all this fail2ban stuff is very much cargo culting in the selfhosting community. I’ve had my VPS SSH server on port 22 with no fail2ban for slightly over a decade, exposed to the public internet (home server is behind tailscale, VPS hosts the stuff I always want accessible from everywhere). Bots try it, they fail, the end. Maybe I’m missing something, but I have yet to find a good reason for the added complexity.
