E-mail has a spam filter. If that doesn’t work, our failsafe is a personal filter system that allows us to create filters, making sure (we wish) any spam that does get past the spam filter gets automatically thrown in the trash (deleted).
The concept of getting a bunch of crap in your inbox didn’t start at the internet, it’s the same exact thing for your real mailbox… except it’s called junk mail not spam. Thinking about that, why don’t more housing complexes (like apartments) set a trashcan right next to your mailbox? It’s not a big change, but that one trashcan placed in that one location will make a big difference to people. Suddenly the stress in someone’s life has been reduced. You just gave them a better experience.
Sometimes all it takes for a big change is moving a one trashcan to one location.

Or a recycle bin.
Is all mail recyclable? If it’s not, you just hurt the environment. Good one! :-p
True. I suppose a recycling been would be more “green”.
