Olx — Increasing sex activities through ads

As all knows that OLX is platform where two people can deal without agent and save his comission..but now a days it is frequently seen that many guys using this platform for hiring / sharing prostitution...they r offering part time job or spa jobs and when they get any girl/ female contact no.they force them to involve in prostitution business for high money amount..As OLX can block these type s of add but No one is noticing this..and only interested to earing through paid ads.
