I'm up to about 10 different phone numbers a day suggesting that I donate to different political parties. It's obvious fraud. they always say about the same thing. since I know that I won't be texting back and forth using certain key words with people, it would be slick if I could have an incoming text message block for unknown people that have certain keywords in it. this way my phone doesn't beep and vibrate 10 times randomly through my work day. would rather keep text to people I care to hear from.
