If you want to try a few ways to fight back and "starve the beast" or at least annoy it greatly here ya go:
1) Go to adnauseam.io and load their extension. It clicks ads so you don't have to and discards the results like a ad blocker. Fill their databases with garbage. Be the "GI" in "GIGO".
2) Try out a WiFi phone. Textplus and others will get you a real phone number and it works everywhere there is WiFi. To keep the number and kill ads costs about $12 a year. How's that for a low cost phone plan?
3) Best for last. Get your money out of banks and into credit unions.
