You really need to be careful with security on Facebook. Nowadays it’s full of drug dealers, scammers and phaedofiles. I no longer feel safe having friends on Facebook, so just use it to follow media. Even though I don’t upload my contacts, drug dealers who scammed me out of my money, when I try to buy cannabis for my insomnia, profiles’ appear on my newsfeed. Legalize cannabis groups are all over facebook, but most members are trying to scam people. I fell for them several times, and away from cannabis, I was also scammed out of €60 on Facebook, after answering an add offering a free iPhone. A lot of the advertisements are from scammers, offering phones, clothes, holidays and anything else they can think of. I recently had to disable the microphone on Facebook, as almost daily, I talk about things in work, only for related articles to appear on Facebook. I regularly comment on articles, only for my comments to be removed or hidden, taking away any social aspect from it. I also know a few phaedofiles, men involved in making teen porn or pimping out teenagers, who have Facebook profiles, but at least now governments around the world, are wising up to this. Take your security very seriously on Facebook, don’t trust advertising or strangers on Facebook.
