Why do some recruitment information in 58 cities say Do Not Disturb in 58 cities?

Look at this kind of website yourself. Everyone can advertise and claim to be recruiting people, and give a little money to open the eyes of scammers.

Can you think with your toes a little bit, is this information more reliable than the telephone poles on the roadside? Do you have to write?

If it is really a legitimate company with normal industry, why can't you even take out your own money to send job advertisements through formal channels and fish in troubled waters on this so-called free website?
