One time I got very fed up with a fundraising caller and they suggested that I re-register to vote but leave the phone number blank, and it 100% worked. Haven't gotten a call or text since.
I keep texting them back, saying I'll give them more money when they get Taylor Swift's endorsement. (Robert DeNiro's text was the last time I donated, but that was also conviction day. 🤷♀️)
It hasn't worked, but it's kept me amused.
Don’t they know that I have recurring monthly contributions for two blue entities? My bank does.
So, they are ignoring that, to tell me that I need to donate? Hmph!
