This is why you don't use the addons on places like that unless you can 'trust' them. Do you really need those 8 versions of "How hot am I" "Rate your freinds" "Add this application or a puppy dies"?
I'd say treat the applications you put on there as you'd treat giving out contact details, but we all know how well that usually goes.
One nice little hole that I've wondered about is the fact that the applications gain access to your information when you add them, a nice box saying:
"Know who I am and access my information"
Unticking this gives you:
"Granting access to information is required to add applications. If you are not willing to grant access to your information, do not add this application."
Why is the option there then?
