I know others have complained too but it seems to be more frequent by the day. Just now I was reading one about feeling the financial squeeze from price rises and starting to feel out of touch with podcasts and friends, clicked next page and suddenly it's gone! Even if there sometimes is trolling, does that mean it wasn't a useful space for everyone to share their feelings in common?
Similarly, "bun fight" threads are deleted if there is robust debate (although I do acknowledge sometimes it's overboard. Or the OP has a privacy concern.
It is frustrating when a thread is offering some solace or you are invested.
