I've been playing with my main, three trial accounts I created and one more trial a friend did for me. I read from somewhere that Blizzard might not like if I play with accounts that do not have matching details (name, address, email?) so I wanted to create myself fifth account that would have the same info as my others. I've tried doing it several times already from home and from work but I still keep getting the error saying "You have created the maximum amount of free trial accounts". I also cannot use the free 10-day friend code as it requires trial account to use. This continued even after I converted one of the trials to fully paid account. I've contacted Blizzard support ~12h ago but they haven't responded yet.

So should I be worried that when I take that friends account and purchase gametime for it Blizzard might look and see I'm playing for a completely different char for a different person than myself and might ban me?
