Which is why I doubt it's a scam in the first place. As said, it wouldn't make sense to scam and steal just a few hashes. It would have made much more sense to accumulate a much more hash power, especially since it has been constantly increasing due to the good payouts.

Also, if it was a scam, he would have probably shut down the servers already so he won't have to keep paying for them and losing money...

I still think that Tomos may be in some kind of trouble or, worse, dead. Or, since he mentioned that he was not making much money and was doing it more as a hobby, he may have just gotten bored or lost interest in this hobby. But, then again, I think he would have still made an announcement or shut down the servers...
