... CF for all their faults probably weren't the bad guy, when they discovered a "customer" absolutely taking the piss with capacity and doing incredibly sketchy things with domains to get around regulatory issues.

I have a courtesy hire car from a breakdown service at the moment with "unlimited mileage". I suspect they mean "unlimited mileage doing the sort of thing you do normally", and that "Unlimited, cool, I'm driving this thing from Scotland to Dagestan" would be met with opposition and a large invoice.

If you were in Scotland or Europe more generally, it'd be illegal for "unlimited mileage" to not actually be unlimited mileage.

If CF decides you're subject to an invisible limit which they won't even tell you and you have your domains at CF, they hold your domains hostage. Luckily, these guys had their domains somewhere else so they weren't hostage. Don't be the one who is.
