Theres really nothing anyone can do about it, but I think the easiest way the prevent scams and slow them down is to educate people that are new to this.
Indeed, there are more fake information regarding crypto and fuds are spreading quickly. But looks like, you're talking about shilling groups where any shit/scam projects are promoted as those will take bullish rally and everyone's will be next millionaires. We can't stop those shillers as they're everywhere and even many of those are on forums to shill projects. So we just need to be aware from those shillings, thus we can prevent any losses, IMHO.
