Thanks Lu, I can understand you wanting to keep an eye of your son's Facebook. More parents should do this, instead of wrongly assuming it is all safe. Especially for young people, etc. If parents did this more it would stop a lot of cyber bullying. It's hard to understand why a positive message on instagram would evoke such an irrational reaction, and as you say, it shows people don't know fake from real anymore. Or maybe the positivity provoked a reaction from someone negative. Keep positive always. It's the only way to survive online and you meet the right people, and it is a positive experience. That's how it should be.
