NO, laalaa, it's "go to hell" but you can say "get the hell out of here!"

This is spooky: I typed in "Go to hell !" then saw your identical post, then both our posts disappeared for six minutes (whaaat?) and then they re-appeared with my wrong comment (of course it's "go TO hell!") and your comment #3. It had also logged me out without me doing anything.
What's going on?

Maybe you accidentally ended up on a different page. I've done that before - suddenly I'm on page 3 when I thought I was on page one. In my case, it's probably using the "back" and "forward" buttons too much.

Nope, I wish it were that simple. Not only did I refresh the page but also shut down the page, went on again and had to log in. And still there was only the original query with no answers.
Very strange, will keep an eye on that.
