Facebook and Samsung - adverts and spam

When I try to read messages on Facebook a Samsung spam message about winning a phone pops up and you cannot remove it. Samsung you are *****ing my airtime and my data!!!!! Get off my phone!!!! Facebook should not allow adverti*****t and spam to pop up all the time. I cannot read anything anymore. I think some of the adverts on Facebook are actually ******* in terms of the ***ual Offences Act. Get the sugar mommies/ Russians ladies, etc. off. It is disgusting and children should not see it. Shame on you!!!!!!!!!!!!!!!How dare you misuse the social media so.
