The difference between fail2ban and reaction is performance. If you are not hitting the ceiling of fail2ban, then you may not need reaction.

Do you have a blog post about your automated fail2ban rule generation?

Why should I have a blog post? I get amazing "performance" out of fail2ban, it does what it's supposed to do and I don't ask it to do more. I've given it "super powers".

Last year I blocked basically all of Brazil. No problems. Who knew?
