I think the point the poster is making is the specific type of disposable address they&#x27;ve used. Addresses on mailinator.com can be read by anyone without a password (go see for yourself). Presumably anyone could just do a password reset and take over the account.<p>However, just because they used a disposable contact email in the whois record, it&#x27;s not necessarily the case that they used the same for the registrar account or anything else (so taking over the domain isn&#x27;t as easy as implied).<p>In any case, I don&#x27;t see any issues with &quot;disposable&quot; email addresses such as a random alias on a private domain with a catch-all.
