Every piece of comment spam I’ve had come through in the past few weeks has tried to disguise itself by using HTML entities to escape letters so that spam filters don’t trigger.  Fortunately, this makes it exceptionally easy to filter out that spam – just block HTML entities.  So as of now, if you type an HTML entity into a comment the comment will be rejected.  If you really need a HTML entity to convey your point, post an entry to your own blog and track back.

Life’s too short to deal with comment spam, sorry for any inconvenience.
