Though not a security breach, it is still an internet crime, a huge one, performed through your systems and you are profiting from it, if CLSTR / Cluster is not an internet crime then what is? 350btc form CLSTR and ~50 from USE, that is around 1/5 of a Million dollars!!

Don't kill your company ffs!
