Well, it's free servers, so whatever he can get out of them will be good.
I believe (from rumours of friends) that most servers actually ban bitcoin mining on their system anyway.
Only the naive believe something is "free"
I can run two machines with 64GB RAM & 20 Core CPUs for the whole year 24/7. Do you still think the return will be less than 1%? I am just wondering how others do mining.
Bitcoin mining is done with clusters of specially designed ASICs these days. GPU mining, let alone CPU mining, isn't viable by a long shot. I'd be shocked if you got any payout at all from a mining pool with it.
