depending on the account. If they are a legit account then I will trust their project. But if that account was hacked, I would never believe it
If an account is hacked, it is far from a fact that the community will immediately know about it. Therefore, do not focus on the lack of a red trust.
To begin with, you can check the message history of this forum member, his trust list, and also whether he has had successful bounty campaigns in the past.
If none of this exists, and the user has been inactive for a long time, it's probably a hacked or purchased account.
