Depends on the site those accounts are on. Itch is not a job market where people present their profiles to look for voice acting jobs. You might talk to people in the job offered community section and any scam with social interaction is practically undetectable by things like a profile. A profile can be easily copied from a real voice actor.
The scams you see on Itch are about games. Sometimes about assets. Mostly it is just trying to have people download malware.
But how could you be scammed in the first place if you are not offering money for the job? Just make sure not to install anything offered to you or to use dubious communication sites. I remember a story about someone that got scammed hacked by visiting some service with a phone. As a developer you are target for scams that do not target users.
