I wanted to tell that we can't say they may not connected as transactions may happen with friends and local people. But the proof of their authentication it is clear that they are connected. And if they break any rules (joining on same campaign/ merit transaction/trust exchange or something like that) then they should be tagged.
If tokens are traded from the yes wallet, it does not prove that they are CONNECTED. Having more than one account in this forum is not a problem. Many DT members have single accounts in this forum.
@Shasan After listening to you, I understand that one can use many accounts in this forum, but not Bounty Campaign/Merit Transaction/Trust Exchange. Doing so will force the forum to tag the DT member account.
I don't know, today I have a lot of doubts in myself, I don't know what to do. But what you say could be true. I'd try to learn a few things first to be able to research the account in depth before deciding what to do.
