Creating a user is luckily very automated, but we have had to increase the amount of information we ask to hopefully screen out bad actors who just want a shell account and then run bitcoin miners (which has happened several times).

Can't you block bitcoin miners via limiting CPU time per user?

As soon as a user hits x amount of minutes CPU per minute, you kill all his programs.

Not nice but effective.
