I just got a fake spam email from a site wanting me to sign up for the Guildwars 2 newsletter, saying someone had submitted my name. Since I've never given my name to them, nor do any of my friends online have my email, I'm sure this is a fake. You might want to be careful and not click on it if you get it.
I had this problem all the time with World of Warcraft spam emails, although with them I played the game.
Guy, I'm sure you're reading this, so if you know who on the Guildwars Team I could forward it to, I'd appreciate it.
