Hi I’m not related to that individual I just found your comment thread doing searches, I haven’t heard of the Lemmy software being able to do IP bans anywhere, would you mind sharing where you heard this information.
As far as I know the only way to do “IP Bans” on Lemmy is to manually block them from the server’s firewall but that’s not a Lemmy software feature, it’s a server feature, and it was also always possible.
