Your lack of trust because you don't like audits they publish is not enough to call someone scam. there's no indication they are doing something fishy.

You can say you don't trust them. I short them :)

For something to be a scam, it is not enough that you don't feel well about it. It means they are defrauding people and there's no indication of that.

If it is delivered as promised, it's ok from the scam-no scam scale. People use the word lightly these days, but they should not.
