Hmm I can see both sides to this.
I have revived older threads, this week I revived one that had died down and people did join in again, it was a fun thread.
I have however had people revive one of mine (about an issue I had) and respond to my first post, no criticism of individuals, they meant well but it was kind of triggering to be reminded of a painful place if you see what I mean. That said, I’d prefer to be consulted rather than just have my thread closed down because that feels a bit heavy handed to me. I’d prefer it if the original poster was asked if they wanted it closed rather than just closing it.
