I believe John Hardin on the SA list has noticed some commenalities and asked for volunteers to check some new rules.

| Mmmm well let's be frank Steve, that’s just simply entirely untrue :)
| The past weeks have seen a rise in image based spam, where many of
| them (the
| ones that doesn’t hit obvious rbl's etc) slip by even ocr plugins
| If you take a look at the SA list you can see lots of people are
| seeing this
| new bunch of image spams and pretty penetrating.
| So far there's no sure fire way of stopping it if you are to judge by
| the sa
| users responses.
| I use spamhaus and spamcop in mta and greylist, and I've gotten a few
| them myself.
| Many of them use the so called "flag" method where the image looks
| like a flag, which is probably whats disabling the ocr techniques.
| If anybody got any advice I'd love to hear it.
