Is there no other ways BTT can track and trace such people posting such project the in the forum?
The way the forum is structured, there is no way to track the accounts that come here to start up such projects. And the forum doesn't check the legibility of projects that are been advertised here.
Is there no way we can run free and fair project in the system without us being scammed or tricked?
The only way is to bring the project to the attention of the forum moderators, and that's only when there are verifiable evidences of scans from the group.
