Re "UserCheck - Block Disposable Emails" add-on:

You obviously did still not read the discussion or the definition for "unmaintained":

That often does not mean much. It simply means that the author of the add on has not logged onto this forum for more than 45 days which makes the label massively misleading in many cases and does not say anything about wether an add on works or not or about the quality of the add on.
