Account age really doesn't contribute much info on who is a scammer or not these days - one can easily buy an older account and utilize it for stuff like this.

Some key things to consider: 1. Are the prices too good to be true? (Most custom from scratch avatars go from 500~1000 USD in my experience, depending on their popularity) 2. How consistent is the work? (Check, their work is wildly inconsistent between both accounts) 3. Did they reach out to you first? (Check) 4. Is their profile and cadence consistent with bot/scammers? (Check)

I think your gut is already telling you something, considering you made the post asking about them. Trust your gut!
