Call me naïve but I genuinely think social media is for the most part what you make of it.
If you follow trash, you will get bombarded with trash, monkey see, monkey do.
Please don't misunderstand me Social media plays an abhorrent and diabolical part in our lives and has directly caused many deaths. It's obscenely evil and Facebook as a company are the equivalent of tobacco or big oil companies.
You don't have to follow trash to get bombarded with trash. It just takes a few friends and even family who are naive, and you will be bombarded with trash by proxy.
