The best part of F@H, vs the others, is that everything comes from one source. Stanford University.
So you need to put some trust in it being from Stanford, run by a acidemically known proffessor. Stanford uses its own university owned servers to send files as well.
THEY ALSO, oops, have avaliable published journal results. So while possible we are cracking bank accounts, or helping Saxon bring down N. Korea single handedly.. Its quite unlikely.
Now dont even get started on the power usage aspect!
