I have a cold reception to all marketing phone calls lol.
They love me, that's why they call me from morning to evening & even on weekends. lol Something really needs to be done to allow a person control over phone calls. Should we have to pay more money to do this though? It should be an option to everyone.
I've been aware for years that telephone companies sell numbers to marketing companies. Likewise some websites do the same with both email & ip addresses.
As for popup windows or other ads on web pages saying your pc is infected, get a fix here, etc. Well on a mac I just laugh sarcastically at their petty attempts. But obviously a lot of people do get caught on these scams.
