How do Scammers Spread my Number?

Hello, On this website I have called A lot of Scam numbers And this week when I called one They Said F*** You, And then hanged up. But this number I’ve never called so how do they know it’s me??

Do they share me wasting time number with other Sourses??

I use the text now app and after a few calls I change to a different number just to trip them up just incase, I know this hasn’t answered your question but in hindsight it never hurts to change the the number you use to call these losers

They don’t share numbers with each other that are time wasters, scammers sell numbers to each other if they are active numbers. I am guessing you called the same call center that you had called before but on one of their other numbers.
