Another Social Security phone scam in The Off-Topic Lounge Posted October 29, 2016 Neither a land-line (which is what I use) or caller ID will stop this craziness. 99% of the illegitimate sales or phishing calls spoof CallerID (one even showed my own phone number calling itself!). I'm also on the Do Not Call Registry and that doesn't seem to help. So, it doesn't matter whether you use a land-line or a cell phone - they still find you. I never used to pick up the phone but just having the phone ringing while I sleep (work night shift) or even when I'm up is annoying, What I started doing recently is to pick up the phone and not say anything. If it is a human calling they will eventually say "hello". It is is a robo-call it waits for me to say something first before giving me the spiel. For those I just let the headset sit on the table for 15 minutes or so. They don't seem to be able to hang up so they have to pay someone for the 15 minute call. That is probably nothing for them but it makes me feel better. As for the IRS scam calls, you should check this page and report them here.
