It might not technically stop scam calls from happening. But I think if they do them at the same rate the indian call centres do them then the scammers will be easier to track down personally and hold them to account.
I have been watching this channel on youtube that has a live stream going were they just auto dial scam tech lines to waste their time. But also they will manipulate the scammers. One of the guys actually got photos of the indian scammers in their office and put it on his computer, so when the fake tech guy saw it he was shocked, then he quickly grabbed a file with VISA on, copied it to his computer and disconnected.. what the scammer didnt realise it was a wannacry-type of virus. So if the scammer opened it on his computer all the scammer network would be locked lol
