It is an Lbank exchange wallet based on their token transactions ending up in a hot wallet. For a while I'm not quite sure all of them are related because the transactions are quite small. Some exchanges apply a minimum amount that can be traded.
I don't know what exchange wallet they use to deposit, but the fact that all those accounts use the same wallet when making deposit, I can assume it's someone's alt.
So far I haven't tagged them even if they get caught cheating on the bounty, it's just a waste of time because some managers still hire them
[account with negative tag] on the bounty they manage.
If indeed all the evidence that I found cannot be the reason why all account can be tag, then I hope that some other cheater hunters can contribute to uncovering it. Thank you.
