I find it hard to believe Zynga had to use such techniques unless you’re referring to very early days. I, too, have used the techniques you’ve mentioned and went way down the rabbit hole. Among the things you’ve mentioned also found myself shipping friends and family laptops and Teamviewering into them to use alias accounts. Not fun to have to resort to such tactics. If Zynga still employs such, I shall make a mental note to stay the heck away from their stock.
