No idea if it's enough start a job board but seems to me like requiring the name of the company and a salary range is not a bad requirement for keeping quality up.
Also, if the job posting doesn't explicitly mention remote/WFH, then we try to avoid posting the job.
I often get recruiters who try to sell me a job based purely on technologies and not what the company actually does. I'll ask them who the company is and they usually wont say, either due to the fact that I haven't sent my CV/resume or they think I am another recruiter that is trying to steal the details.
