Are you paying on stake account or on users addresses?
If you are paying on users address and you add this address on the spreadsheet it will help to find abusers, some users use even 50 accounts here on the forum.
Steve is paying through the website,straight to our accounts.
Its real some even have hundreds and have a small time company in spamming sigs in this forum,the usage of direct bitcoin wallet payout will be useful to eliminate spam yes,its up to steve if he'll change the rules to that.
Why would someone be dumb enough use the same address multiple times on different accounts though?
