I do not know how I missed that before. Not commenting on the linked thread from 2015, the wallet connection seems very solid. Opinions?
If the wallet doesn't belong to a shared service like an exchange (doesn't seem so) then the connection is solid. I haven't looked at the bounty abuse part of it.
Did mhanbostanci provide any excuse as to how "different people" used the same wallet?
There is signed message in that post, you know...
