Social media channels are only way where team, let investors know the Update. So obviously investors should up-to-date with those project's social media channels. But i think some project's team should be more careful! Like announcement swap their token and give 2/3 moths max for done the work! Thats sounds like phishing, scramming cause thus they can grab lots of tokens from them who failed to swap within time.
And with social media, many are also being victims of fake airdrops, marketing, and projects. There are scammers that do buy pages that have a lot of followers for them to easily make people think that they're a legitimate project because have followed them.
But little did people know, not all of them are for real as many of them have just bought those pages for them to easily gain traction from their potential investors and they can show that they've got already made a brand themselves. And from there, they can also phish those people that have no idea if they are real or not.
