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.
The apostate thing won’t always work. It requires a couple of steps. The terminology you want to use is to say “I’m DF’d” or “I’m disfellowshipped”. That means they are not actually allowed to talk to you. They won’t even say okay, they just leave. Works 100% of the time IME.
