Helltread is a fun nightmare.

Hundreds of users are tagged in the same note, so everyone one of them will get a notification for every reactions that note will have in the future (like post zap or comment). This imply this notes is also very long because many client don't implode the visualization of all the users tagged in. Basically many users had their notifications unusable for a day, unable to check the resto of their notifications.

Non the less, the thread has no end since many just started complaining about the ones that still were replying, making de facto the thread even longer.. it was a dog trying to bite hi tails.
