Sure, you can go to the scammers' website and you can ENTER your number, but that will NOT stop the calls. It has the opposite effect because you are CONFIRMING your number and permitting the scammers to collect even more info about you (such as the IP address you were on when you visited the scammer website). They sell and trade confirmed numbers with other scammers, and your phone number will be on even more sucker lists and you will get even more junk phone calls.
That's what happens when you enter your number on a scammer website.
Are you part of this filthy scam, or hopelessly stupid? Probably BOTH.
