So you find a module, and like it. But due to an email problem you think it should be delisted so that neither you nor anyone else can use it. It is unclear to me that anyone at all benefits from that.

There have been suggestions in the past to delist modules that never worked from the first time they were uploaded, and have not been updated in over a decade. Those suggestions have also been rejected by the PAUSE admins.

However there are mechanisms to become the maintainer or co-maintainer of a module whose original author no longer has the time or inclination to maintain it themselves; I believe in rare cases that can happen even when the original author cannot be reached to give their blessing - but it would take substantially more effort than "I tried emailing them and it bounced".

Update: I ++'d your node despite strongly disagreeing with the content, since I feel that the provoked thread is beneficial to PerlMonks.
