Yes. I have. I listed many alias who i thought were manipulating the price action earlier in the year and those who were bashing BCAP and RIGH. The guy i spoke to went onto ihub while i was on the phone with him.  We went over many posts.  I told him IHUB was a haven for criminal activity and posts dictated trading on many occasions.  I proved my point with real time last sale and level 2 data i recorded during the day and sent in the data along with posts that followed or preceded the action.  Alot of work but i managed to capture illegal activity.  Staged sell offs, selling below the bid.  Pump n dumps.  Anyway at most i alerted them to the corruption and market maker manipulation.
