I mostly notice that a lot of scams starts with "falls advertisement" or some people invests on crypto because they saw an advertisement. Which is why, UK released regulations on crypto ads to Ensure They’re Fair, Clear, Not Misleading.
"New rules will increase consumer protection while encouraging innovation."
-UK Government announcement
Honestly, I think this will actually be a good move, since most of the advertisers just go ahead and advertise things without knowing about it as long as they get paid to advertise.
