theres been a lot of back and forth in this thread with a lot of information that could be accurate and could not be accurate along with a lot of assumptions people have made from information they gathered that could and could not be correct.
so here is whats going to happen, im going to lock this thread, because at current there's no way the people who are deep in discussion in this thread could stop going back and forth and get on the same page, and thats only going to lead to more people trolling and me (or someone else) having to get involved later to break up an even more involved thread.
no one knows how blizzard deals with things we can only guess. so i would go with what the 2nd poster said, to get a new one since blizzard does have access to that information, and if their computers aren't linked to find it, then a human who has access to that information could easily link your old activities back to you. obviously that's not what you want so the more new stuff you can get for your new account the better off you'll be.
Thread Closed,
Have a nice day.
