I browsed the tubes for a bit and couldn't find anything but the following, which is a Feature Request comment under Backend[1] mentioning a "controlled backdoor", possibly added by this contrib[2]. It reads as follows:
at the cost of getting scorned, but dead serious: a controlled backdoor, with an automatic audit trail, to be used by lawful agencies for keeping us safe. Bitcoin by design supports criminal activities, which undermine the community. A community messaging system should have a way of cleaning itself.

Probably not the example mentioned by Parent, though.
