Some “friend” you’ve got there. I hope you’ve punished him sufficiently, say, like screwing his nuts in a vice and shaving them off with a belt sander.
That said, I can only recommend that you use a gMail account for your emails and set up an extra email alias for really important things like account credentials, bank stuff and private matters. (or the other way around)
I think you should go ahead and prove the connectivity so that a mod/admin can go ahead and make the decision. Personally I think it’s a given that you’ll have your old rank back, but it’s not my call to make.
Also, great choice on the new nickname, I like it! 🙂
