Sparky, The Do Not Call Directory does a good job of blocking calls from legitimate telemarketers. The scumbags who spoof legitimate numbers don't give a sheeeeet about this Directory.
Real person called said he was from The Veterans and wanted me to give a donation over the phone. Told him "no" and hung up.
Really since when do the Veterans call your home number and want money? Scam
Someone called from 267-666-6325 and asked for a person I don't know. The person got a bit sarcastic with me. She asked if I don't know anything and she would not hang up. She asked why I would like and she laughed and stil would not hang up.
Called, left no message, presumed to be a telemarketer or scammer. I'm on the do-not-call list so that only seems to be helping with the more honest end of the spectrum with these people. I enter the number in my phone & ID it as "scammer" to insure that I never accidentally answer.
