I suspect that the owners/operators of Ice In Space are pretty much like us - they have families, full time jobs and other hobbies, so spare time would be at a premium.
They do not have the resources of say, legal systems, financial systems, law enforcement, etc nor do they get salaries for their "spare time" work in running the Forum and dealing with the unwelcome and unsavoury dishonesty when it arises.
A difficult balance to get right.
Just my 2c worth.
