I am not on the list because I cannot guarantee that some chip I might buy at auction won't be posted by a "slabber" under an assumed name. I also didn't like the negativity if "the pledge".

I am member # 12 of the Slabfree chapter and support their professed goals of education & information.

One reason there are more on the "list" than in Slabfree might be that it costs $5 to join Slabfree
