yeah, they were vouched for. but, for example, others were not and are still hidden (https://news.ycombinator.com/item?id=50273618). and apparently this one, too.
the most annoying part is that i got no indication that i was suddenly shadowbanned. if someone didn't tell me, it would have probably been a day or two at least of wondering why i had no engagement on my comments.
no notification, no appeal system outside of email and pray. very cool system.
Informing the subject they are shadowbanned would kind of defeat the purpose of the shadowban. Might as well just issue a regular ban then.
It's nice that this place maintains an email endpoint that's actually staffed by humans who can intervene if needed. That's more than can be said about most places these days.
