The list is reserved for those who were instrumental in substantially ripping off folks in the cryptocurrency space. Real names only unless warranted (e.g. TradeFortress - not yet added hoping to have real name revealed). Please provide links in cementing your claim. Refrain from suggesting staff of this forum unless the evidence is overwhelming (none come to mine for me at this penning). Feel free to offer up corrections and middle names for those listed below. Apologies for not providing links for all the entries. Adding links (ongoing).
