Yes and no, if you scambait hard enough your number can eventually be added to a blacklist for larger scam organisations that bought your data for use in multiple scam attempts.

In my experience that has really cut down on the calls.

In 2020 the department of human services accidentally posted my personal phone number on a list of support services for people experiencing housing or food insecurity. This number was then circulated by every major news source in my state. I couldn’t change my number at the time because I had no legal ID (still don’t… Can’t figure out how to get ID without ID, but I have a new number now at least) at first I didn’t really notice the ratio of spam calls to genuine calls for the wrong number (ie, people calling my number because they needed housing/food) . I just remember getting 40+ calls a day at many stages.

But as the actual number for the food relief service was circulated, I eventually stopped getting genuine calls and I was getting 3-5 scam calls every single day.

After a year of scam baiting, I was getting 2 a week.

Now, I’ll do something online that requires sharing my current number, within a few hours I get a scam call because my data has been sold, but I bait the heck out of that first call and I usually don’t receive any further calls which suggest my number was blacklisted by a larger scam organisation, and I won’t be hassled until my data is sold again as a new item.

It’s hard to avoid getting your number on scam lists when the largest health insurance company, and the second largest telecommunications company in my country both had major data breaches where millions of customers identifying information was accessed and sold to scammers…
