I remember back as a kid we still had telemarketters on the landline but robocalls were super rare, if, never. I used to enjoy having fun with them and doing stuff like playing along with their marketing but constantly interrupting or putting them on hold randomly, just to tie them up for nothing, then at the end just saying I'm not interested and hang up after wasting like 20 minutes of their time.
I had a landline at home for a while since I just got one kind of by default when I bought the house since I work for the phone company. But over the years I found I could really do without it so I just have the cell now.
