As we all know, the EOS blockchain will be unique in that token holders can bring complaints to the arbitration system to right wrongs.
I am using the EOSTalk forum because it records all interactions on the Steem blockchain and is therefore a safe way to record the claims without fear of text manipulation.
Please record your complaints in the comments with as much detail as possible. Please DO NOT write down your private keys as that will just open you up to more scammers.
You can submit a formal complaint here, on the ECAF site:
https://eoscorearbitration.io/file-a-claim/
List your claim on these forums to gain visibility and see who else was scammed by the same person(s).
