I’m rude to debt collectors who call me trying to collect debts from people who happen to once have had the same phone number as I once did. Like, I’m not who you’re trying to collect from, fuck off.
I’m also rude to generally any scam caller, they’re some of the few people I take great pleasure in telling off because I can get away with it. They’re scammy assholes, what’re they gonna do? Cry to the authorities? Knowing that they’re pieces of shit who scam people out of money? Good fucking luck.
I think it depends on where you live. In my case, I see about 4-5 a week on my security cameras, but only a few a year ignore the sign. On nextdoor dot com, it’s discussed and video camera footage is shared, so we know which neighborhoods are targeted. Mine is because of the aging population of upper middle income folks.
