I like the idea of wasting telemarketing company resources, but we have to remember the people calling us are actual human being forced into shitty jobs where they suffer abusive management thanks to capitalism. So “torturing telemarketers” sounds bad to me, as does being rude to them or leaving them to talk into silence.

I usually pick up the phone, announce that I will hang up in 20 seconds, wish them a good day and then block the number.

I used to get 1-2 call per day, now it’s more around 1 every 2 or 3 weeks.
