How could you possibly compare that to > we may also wildcard your DNS to localhost and set the TTL on your zone out to a year This is going way beyond suspending a customer, this is an active attack by EasyDNS.
It does indeed go beyond a suspension, it's a ban , and that's why I equate it to Amazon and Google blocking any new accounts - they are banning you from their platform, arguably for life. At least EasyDNS offer it to be 12 months. I'm no DNS expert, but AFAIK, you can transfer the zone to another provider (one that you don't violate the T&Cs with) and from there you could conceivably regain control over the domain.
The TTL tells DNS resolvers to cache the "localhost" result for 1 year, it's specifically an attempt to prevent you from regaining control over the domain at another provider.
