I have been looking at the contents of some spam I am
receiving, and some of it is getting pretty gnarly.
One thing the spammers seem to be starting to do is to
break up words with one word co<!--Brown-->mments.
One way of dealing nicely with this might be to take a
pass through the e-mail and move all such comments to
the end of the file.
As well as reconstituting the words, so they can be
more usefully dealt with, this might have the added
bonus of potentially making the spam _more_
identifiable if the spammer tends to use the same set
of words in their comments.
