I've been using Facebook for over 10 years, which is around 2011, the account is still running active, I don't get the reason why people get banned from the number one social media on Earth. It is well written about their rules, which anyone should abide to. When at this time, Facebook doesn't hinder anyone from sharing links to their platform. It depends on the kind of link your share on Facebook. Facebook allows affiliate links, website links, blog or forum links, and other earning means too. I've been sharing majority of this links on Facebook, still I never received warning s for it. Because, I don't share it anyhow, I share when their is need for it, especially when I am private chatting an individual there. Remember, Facebook doesn't accept nude, it is against their rules, if you share such, then it means, you want to get your account closed permanently. First thing I do when I enter into any given platform which I want to use either for earning means or advertisement, I read through through their FAQ, to know exactly what it's rules is all about and abide by them, maybe assume you read Facebook own, you could've understand.
