Some specific signs that newbies can spot in scam projects early are:
Unrealistic promises of high returns or guaranteed profits
Lack of transparency or verifiable information about the team, the technology, or the roadmap
Fake endorsements from celebrities, influencers, or reputable organizations
High pressure tactics to invest quickly or miss out on a limited opportunity
Poor grammar, spelling, or design on the website, whitepaper, or social media posts
Poor grammar, spelling or anything that doesn't have to do directly with the project doesn't mean the project is a scam. Sometimes it might be they hired an unqualified community managers and they haven't noticed the manager to be inexperienced for the job. The management of social media is a community manager Jobs.
Some projects teams are anonymous but that shouldn't mean they're a scam, nobody knows Bitcoin founder but bitcoin isn't a scam and we have some other projects like Shiba Inu and they aren't scam. Some projects founder don't like to be the face of their invention but allow the community to be incharge.
Any project that has fake endorsement is a scam, as no real project will want to associate their projects with fake things knowing that if they get caught they'll lose their trustworthiness from their community but scam projects don't care, they're just lookimg for ways to trend so they can get more victims to scam.
