A lot of the independent vendors in onionland are scammers. Eradic, all or most of the Tor Shops, etc. Stick with the centralized markets. The best wiki right now is probably Evil Wiki: http://wvk32thojln4gpp4.onion/wiki/index.php/Main_Page Second best would be Cleaned Hidden Wiki: http://3suaolltfj2xjksb.onion/hiddenwiki/index.php/Main_Page You can find chans and forums on them. I don't know which ones are popular.
