To the OP, call the attention of the people behind the project to clear this out.
Its not the project that is scam, that is a random guy who is trying to impersonate the Terra-Credit project using a same
Facebook UsernameDoesn't make sense of a team member to do that because it will ruined the company's reputation here, unless he went rogue but I seriously doubt it.
If its a team member but its not. Its just an opportunist trying to use them.
Take a look on this:An original page owner should have a tagged like this on his account.Anyway I hope this isn't a dev on the project and is just a social media manager, imagine trusting someone to build a blockchain who can't even come up with a strong password.
Its not hacked or even their manager. Its just someone using their name to grab some frew money. Its not new, it is happened as well on other project like Ledger but unfortunately Facebook have ways to know if they are original or not.
OP, you should alert the project to report the imposter on their page so facebook would be aware.
