What does this (wrongly) association have to do with the subject? Topics open to talk about this, not to talk about peripheral issues. If you want to talk about the association of other accounts, you should do that in the appropriate topic here.
Incidentally, I am not a fan of sportsbet.io, given the way in which many people have been duped. But on this issue I can only say that it is not the responsibility of sportsbet that many bitcoins have been gambled, that is your own responsibility. Nobody has obliged you to deposit the bitcoins. I do not think that sportsbet.io should return the bitcoins.
