I guess this just happens to new users, I have an account with the same username both on Hive and Blurt, but it is because I was part of the original airdrop of each platform, so if you find the same article of mine on two or three platforms I would have no excuse, the accounts are mine. I did not have to even create an account it was created for me. I do post my Actifit report on all three platforms. But I guess all new users should create accounts on all three platforms with the same username to avoid what happened to @quentindeschamps.
