Uhhhhhhh... real people live in those countries and might want to use his site? I'm not saying they are entitled to his service but the amount of irrational paranoia people have over port scans and SSH bruteforcing is truly phenomenal.
Nobody anywhere has an automatic right to use any service on the web. Half of Europe can't visit US sites because instead of complying with the law they decide to take it out on the citizens. That's fine by me. Corollary: it is also fine by me that parties that have weighed the ups and downs of serving certain countries have decided that the balance is in favor of blocking them outright.
Portscans and SSH bruteforcing are not necessarily the problem, but they can be preludes to a problem.
