I'd never heard of that before. I wish it were a thing where I live. But at least in my apartment complex, the recycling bin is right next to the mailboxes, so I can conveniently just move the junk mail straight from my mailbox to the bin.

The interesting thing is that there was a sticker inside the mailbox already, but it didn't work, my mailbox was filled with junk mail, and I put them in the bins too. I guess the others don't mind the flyers and stuff, because the bins are still pretty full, every time I check my mailbox.
