I guess you could use Blacklist to do some of it. Add a common derogatory word used in the subject posts and then run the cleaner. Don't forget to remove the word when you're done, unless it's a really nasty one like "the N-word" or "French".

YEah, it's the n-word. the trouble with that is they spell it with letters and numbes to disguise it.

Bastards.

You should be able to delete (or rewrite, mheh) comments at your Nap Room login, Manage Weblog, Edit Entries, select the entry from the list. Scroll down from the text of the entry to the list of commenters. You should be able to delete it right there, or you can click on the commenter's name and just delete or change it one word at a time.

Unfortunately, there's no easy way to see all the comments at once.

And ignore the wankers at Blogcritics.
