While free weekends are generally a good chance to try the game I'm genuinely concerned that some people are going to use this as an opportunity to create throwaway accounts and do pub stomp streams and the like. We all know that this game has a bit of an issue with smurfs already, the last thing I want to see are people logging in, boosting accounts, then selling them before even paying for the game... This could ruin the experience of the weekend for a good majority of the community that already exists and completely turn away genuinely new players. I hope Blizzard has something planned to check for and catch this kind of activity.
