I get the usual spam aimed at personal numbers, plus an amazing array of business-to-business (OK, mostly scammer-to-business) telemarketers.
I can't tell them what I really think for fear of being Google-bombed...
What do you mean, no choice? Whenever I get one of those popups that says they want my cell phone number "for better security", I click the "no thanks, maybe later" option.
Of course, all that's for nothing if they can dig up phone numbers by any means necessary.
My cell number is also my business phone, so I had to provide it to create a merchant account.
Real computer scientists like having a computer on their desk, else how could they read their mail?
