I don't think we need a front-page story on every rumor or every tweet he makes, and for some reason commentators on these stories can't seem to follow the guidelines (https://news.ycombinator.com/newsguidelines.html).
Most of the "breaking news" stories have turned out to be false anyways. Nobody's intellectual curiosity is being satiated by this nonsense.
I propose a 30 day cooling off period. There are other outlets (e.g. Twitter) for folks who really want up-to-the-second news about Twitter.
We don't want to suppress the topic altogether because when significant new information (SNI) does appear, it's important to have a thread about it—and if we don't, there will be a user rebellion in the other direction ("I can't believe this isn't on HN, I guess it's not a news site any more").
(Also, it isn't possible to suppress a topic altogether - users will just work around whatever automated restrictions we put in, and manual restrictions are inevitably partial.)
The solution is to allow the submissions that contain SNI and to downweight the ones that don't. By downweight I mean that users can add flags and mods can add additional penalties.
This solution is imperfect because when there are so many raindrops coming in, we can't dodge them all - but at least the worst copycat/followup posts, the ones that just repeat what has been said elsewhere, shouldn't stay on the front page for too long.
