blocking ip addresses

The best thing to do is work off your anger and frustration by submitting a post full of f :x :? :evil: :shock: ing expletives to Linode forums :)

Then, if it's not bogging down your machine, block their IPs and forget them.

If you tar pit them or similar, they may well respond by having one of their botnets launch a DoS attack against your Linode, then caker has to null route your IP, then you get so mad that your head explodes.

You can try blocking specific countries. If they're using your webforms, then try mod_geoip. If they're using smtp directly, then you can use an iptables filter program to block that port to specific countries.
