There's a few ways to do it; but if they block based on username it can lockout legitimate users too.
This is what fail2ban is for. Too many failed auths from an IP and that whole IP is blacklisted for a day or two. This can still catchout vpn users, but it's still less disruptive.
Many blocked for an hour or even just 10 mins. at the time it was enough to get the attack scripts to change targets.
I went a bit overboard I think with my fail2ban configuration. If you fail 2 times to login in any admin interfaces (ssh, web, etc), you get banned for around 4880 days.. I have too many banned IPs already.. :/
