As many game makers make it very difficult to delete game accounts, I wonder if it would be helpful to provide technical instructions for how to delete accounts for specific games. Actually, I wonder if such instructions are available on the site and I haven't run into them yet. If so, perhaps we should make link to these instructions on the list of addictive games or some other obvious location.
I personally have struggled with how to successfully delete my WoW account. I tried both uninstalling it, deleting my characters one by one, and changing the password to a random word. None of those were successful (I am glad to say why they were unsuccessful if someone wants more narrative); however, I just signed over my account to someone who will never give it back to me. I am no longer tempted by the thought that I could access those characters again.
I have also struggled with flash games and movies. I have uninstalled flash to provide a barrier to impulse playing, but have recently had to reinstall it for work. I would love to know if there were some technical way to allow me to use flash for some of the programs I need for work, but disable it for online content.
