Yeah, I know that it could be gotten around and even abused by some little brats, but what I'm trying to do is "popularize" some sort of security method.
Sure, I know that there are certain ways to block this or that and stuff, but how many average users actually know how to implement them? Of all the typical users that I know, I can't think of more than a handful who could even figure out how to use the existing blocking methods.
If, however, they stared at an "Email PIN" field every time they created an email, it could become a useful tool that, in general, cuts back on weasel spammers.
Thanks for all your comments.
