> Take a look who is they registrar and then look their prices up.
So, in case anyone is interested, their registrar is MarkMonitor Inc., with a pricing of "contact us". The only pricing info I could find [0] said that it's 20$/yr for a .com, but with a minimum spend of 10k$ (probably reached by using their other services, such as the stated purpose of monitoring of trademarks).
If they have a customer like steam would they just cut off the domain? Probably not.
Other domain registrations would just ignored this and nothing would happened.
