Cant contact advertisers

<p>Now olx want my cellphone number before they allow me to reply to an advert. Absolutely no way. Why would i trust olx with my phone number. Big data is massive business these days. My number be eventually be used for direct marketing and sold on for more inwanted marketing or even worse. Sms ****s etc etc. Olx do absolutely nothing to follow up on known ********, what would make anyone believe their intentions are good with oir cellphone numbers</p>
