In all honesty, Facebook is getting a little too nosy with their more recent apps such as the relatively new messenger that they require you to install on your mobile devices- Many friends of mine have had people they've never mentioned outside of the messenger's voice chat, and had no mutual friends, with begin showing up on their recommended-friends list. The website is, for the most part, trustworthy, though I recommend that you watch carefully for what Facebook requires permission for- desktop and mobile.
I have also marked Facebook for spam, discrimination, religion, politics, and malware due to the obscene [IMO] amount of game invites and newsletters showing up on news feeds, even for blocked games in many cases, as well as the many people trying to convince others that their way of thinking is the only way a person should- though this is purely reliant on who the user allows to show up in their feed. Malware is marked due to many Facebook web-apps recently becoming security threats, and many people (such as my family members, friends, and even a handful of strangers I've talked to) reporting that Facebook is one of the few, if not the only, sites they bother using. Almost all of these people have reported their computer getting slower each time they use Facebook, and not speeding back up after they exit out, restart their computers, or do maintenance. In some cases, some people have reported getting malware from certain facebook apps.
Be careful with what you do while on Facebook- It's a useful site for staying in touch, but recently it's become a lot less innocent than it looks.
Un buen sitio pero cuidado con la privacidad que Facebook abusa bastante de ella. Yo lo que hago es que si no quiero que una foto sea publica no la pongo. Aunque solo la vea yo no la pongo pues los derechos de la foto pasan automáticamente a Facebook.
Have had trouble in signing in my password was forgotten by the server..so I have spent some considerable time logging back in..in all it is not too bad..we have to remember it is a site for all to enjoy..One point I find amusing.,. It is a site not for Kids under 13 years why then has it a suitable for kids rating.,.
