What do they have in common? They all joined the same bounty campaigns run by Sylon and no other bounty campaigns. And they joined the same airdrop!
Why would they only join Sylon twitter campaigns? His twitter campaigns don't require reports. Basically the same user created multiple accounts and twitter handles to get more stakes. So the three above are the same people.
*mic drop*
There's other users who follow this pattern too. What do you guys think?
