Unlike physical property domain names can't leave the Internet so you do not have to look too far for them, that being said I have on multiple times either bought stolen names unknown to me that were taken back by registrars, had emails attempted to be broken into, had accounts broken into, names transferred against my will, helped ( I lost count of how many )people recover names that were "stolen". So yeah trust me my good man, we understand but in this case I think you are going to be just fine
Moniker does not steal customers domain names so with a title like "Moniker removes domain from my account" Domain Theft! it is (you have to admit) a bit sensational and a bit of an overreaction when you did request for them to move the domain name from your account. When people post things like this and hundred or even thousands of people read it not everyone always takes time to read the details in the thread and also might not fully understand what occurred here or did not occur so you might just want to be a little more careful when claiming a well known reputable domain registrar committed "Domain theft!" this is just my opinion and since you are here on a public forum we are all entitled to give one.
I seriously hope all this works out but it might be better to not jump to conclusions or at bare minimum not put such a title on a thread like this in the "Scams and Warnings/Alerts"
