I don't do a lot of comparison reading of the TOS on a lot of hosting providers, but this stuff doesn't seem as unusual to me as it does to you. Most providers will shut you off if you're running a server that attracts a lot of DDOS attempts. Many providers explicitly disallow running irc servers up front to avoid this very scenario. If your site is constantly getting DDOSed for whatever reason that is going to have a big impact on the hoster's entire network and other servers they are hosting and while it may be through no fault of your own, almost all hosters are going to bounce you if it is a recurring problem.
