Are you allowed to sell it?
Aren't private selling of accounts liable to get suspended.
No it will not get your account suspended but you are at risk of having the seller recover the account so escrow does not matter.
3.5. Warning concerning the selling of a ZenCloud Account.
ZenCloud does not officially support the sale of a ZenCloud accounts
between private parties.
A possible vulnerability has been identified that would allow an
account seller to keep control of the account even after the buyer has
changed the password. This would allow the seller to essentially take
the account back once it's been sold.
We are working to fix this, but the best course of action is to
NOT buy or sell an account from any private party until another
announcement is made concerning this issue.
