What do you do?
I have two large signs on my letterbox. One says "NO ADVERTISING" and the other "NO REAL ESTATE ADVERTISING". In spite of this I still get junk mail, particularly from real estate agents. I thought of going around to their offices and walking in and dumping my own rubbish on the carpet, but so far I've resisted the temptation. It's especially annoying when I go away and have stuff hanging out of the box like a red flag to thieves.
Any suggestions for how to stop this?
