What happened?

Literally just pressed send on a starter, the website asked me to verify myself. Then the person I was typing too just disappeared:( I don't think they did on purpose though, as it said my message sent.
I can't remember their username, I think it was backandforth something. My adhd doesn't help in these scenarios.
If your reading this please come back, I can't find you anywhere so idk what happened lol!
Love, Emi
