Attention new posters. Beware: ACF is under attack by a small number of trolls who post false and misleading replies to questions here, and run campaigns of lies against some of the long term regulars in order to get them killfiled.
These are my recommendations to filter their malicious trollspam
By filtering out messages containing firstname.lastname@example.org << q34wsk20-at-yahoo.com>> AND <<email@example.com>> in the "From:" header and messages containing "ccountrynet" in the path statement you will knock out more than half or even three quarters of the trollspamming in this group.
I also recommend filtering all crossposts, anonymous remailers, and any posts with these providers in the path:
eternal-september.org dotsrc.org ccountrynet < especially this one individual.net easynews.com anonymous
