old account 'nonexistent' got suspended all of a sudden. finding the lost friends.

I don't know if the mods would accept this or not but my account got suspended 2 days ago for no reason. I had a account before that too and that too got suspended the same way also. idk whats the reason, if anyone can tell. So since it got suspended suddenly, I had some very good friends there so I am having difficulty finding them since I don't even remember their usernames. Never paid towards them. Anyone who I was talking with, do inbox me right away. Thanks.
