As I said, to avoid discussions on how they’re tackling it, more often than not - scammers are amidst normal users on social platforms. Its important to not make everything available to prying eyes.
It is something that most of the projects have to work painfully with the social media platforms (especially for cryptocurrency and gaming), Cardano was exposed to this scamming platform for the first time. There have also been lawsuits for example on YouTube recently by other projects, but unfortunately results are really working with one on one channel/account basis, with every report.
What would also be good is for people to report such channels (not videos as videos are hidden quickly) to Telegram group below:
If you’re not on telegram, we are anyways capturing channels on forum and adding ones not raised before to the list.
