Well, Earthsc is a contribution based forum where it is super easy to join, but to do so requires a $10 a month contribution to the Coop. :) We call it the troll filter. :D Also, if people cannot afford to donate a pack of smokes per month to help out our initiatives, then they are basically useless to the organization in the first place. That is not meant in an insulting way, it is meant in a practical and serviceable way. :)
