As we all know the spammers insert special characters in the middle of subject words to bypass the filters, e.g. P/O/R/N, or all sort of other variations.

Can a test we devised, similar to the COMMENT test that counts the number of special characters or detect similar characters appearing in the middle of words.

I guess one way to approach this is to first count if there are more than 1 or 2 special characters and if yes then determine if they are followed by text.

This could be a weight test.

This does sound like a good idea. Our spamtraps don't seem to get much spam like that, but a test looking for non-alphanumeric characters that are surrounded by alphanumeric characters might make some sense (which would catch "P/O/R/N").
