I don't think that would be considered SPAM. Especially when it is being linked from his own site. He has given us a link to his site, which has a nice selection of free
ENF-type stories. If the link from this site went directly to the CFNM site, then it may be considered SPAM. But his site is free, it relates to the theme of this forum, and he's made some pretty good contributions here as well.
BTW...I really hope this thread gains momentum. Great idea!
