They totally ignore the email send to them or set it as a spam message but i believe their Facebook, instagram, twitter and LinkedIn account is still active, it just that they dont usually update it.
I will advise people to report them to the company (Beosin) that audited their smart contract.
What will happen if we report the company? I don't think these companies even take bounty hunters seriously as many companies haven't paid their participants and still functioning well and I guess in this case investors did get their tokens.
I don't know what will really happen if the company is reported through their smart contract audit company atleast they could contact them and advise them about the situation cause if their bounty participants dont cool off it may affect the project in the future. But their investors did get their tokens.
