The thousands of subscriptions are a nuisance. Dozens of emails coming in every afternoon. It'll take hours to undo them.
I'm sure I'm not the only one who has been around a decade and who doesn't want the instant connection with every post I've ever made.
When I quote multiple posts, it remembers my selection, even when I go to the next page. Even adding a feature like that to select threads to delete would help.
Years ago when the same thing came up over private messages, they added a delete all bottom. Why don't you do that here, too?
Maybe I'll just change my email.
