This particular spam's text is in an image, which makes spam removers totally

Actually SpamAssassin considers an email message with just images in it
to be highly suspicious.
It uses a configurable scoring system based on a number of criteria, and
particularly in a forum where the rule is text-only messages or
mostly-text messages with very small attachments, it should be possible
to configure it to zap out such spam pretty reliably.
Baysian filter systems, such as are used by Mozilla and Thunderbird, are
of course useless in filtering such messages, as well as messages with
"word salads" included in them. But SpamAssassin's quite a bit more
flexible than that.
Sorry, this is getting pretty far off-topic ... but maybe somebody'll
find it useful for something...
