In some countries, job ads placed by agents are really just to attract job applicants to send their CVs or resumes over. Why do the agents want to collect and accumulate the CVs and resumes? This, I do not know.
There are no jobs available at all.
One may notice the 'very attractive' pay or other benefits that are published in the job ads. Well, you know what, when something is too good to be true, chances are, it really is not true.
