Josh Centers, TidBITS:

In a Hacker News thread about Dustin Curtis’s locked Apple ID (see “The Mystery of Dustin Curtis’s Locked Apple ID,” 5 March 2021), there were several reports of iMessage accounts being disabled after other users inadvertently marked messages from them as spam during deletion (swipe left on a message and then tap the trash icon).

Follow the link for all the details. Not going to test this (something I usually try to do when I run across stuff like this, but just don’t want to fall down that sinkhole).

But worth noting:

If you regularly delete messages or conversations in Messages, read the prompts carefully before responding to them.

Awareness raised.
