I just emailed their support regarding TOR and two emails latter my account was blocked as well as my wifes (referral) which we used to see if they can be trusted what they say and they failed to do so.
They failed your trust test because they blocked an obviously fake referral account?
You tested if you can cheat them and since you can't in reverso world it means they are cheaters too? Common!
Not saying that you should store your coins on any online website but I can assure you every single one of them would block your account if you try this scheme to make some extra income.
My keys, my Bitcoins with at least having some anonymity.
What you want sounds like sending an anonymous letter to a broker telling him you have 100k under your bed and you want to invest that but keeping the money in your pocket. "You can't have your cake and eat it!".
