CrowdSec has completely replaced fail2ban for me. It's a bit harder to setup but it's way more flexible with bans/statistics/etc. Also uses less ram.
It's also fun to watch the ban counter go up for things that I would never think about configuring on fail2ban, such as nginx CVEs.
Edit: fixed url. Oops!
Wistram from The Wandering Inn. With all the secrets, drama, bureaucracy, and faction infighting it feels like a real school.
That being said, no way would I attend that place. I'm going to stay the hell away from that place and watch with popcorn at a distance.
