Social media exchanges amongst school kids has got a lot to answer for. Bullying is not only physical but mental too.
Social media bullying is obviously huge these days. I dont doubt bullying happened offline 20 years ago, but it's so much easier now on social media, and probably less easily stopped.
Parents allowing their kids access to social media too early, and not monitoring their use is a key issue IMO. My son is 11 now, and has in the past year got a phone, which he does jobs around the house to pay for. We got him a phone on the very condition that we will be checking the use until we have confidence that he can use it appropriately. That means checking his browsing history, checking his messages he sends/receives from mates. Some of the things we've seen on his phone are amazing.
Yes it's a slight invasion of privacy, but he's young, still a child, and with the best will in the world may make mistakes - it's natural. I just want to make sure we are comfortable he is making those mistakes in a relatively controlled environment to start with, so it's not too late when he makes the mistake of replying to a fraud message, buying in app purchases etc, or being implicit in bullying, or anything else that could happen. We also have an app to control the usage of his phone. He has a maximum time limit per day which he has to do as he wants on his phone, after which the phone shuts down and he can only call us or emergency services on it.
I see the first year or so of him having it under our monitoring is just a learning experience for him. The alternative is that he doesn't have it at all, and he prefers having a phone under supervision than not having one at all. We used to check it every night, but now we check it far less often as we've built up greater confidence that he knows how to deal with situations that arise - maybe once a week or so now.
Fortunately there's only been a couple of minor incidents where I've had to have a word with him and speak with him about his use. This might have been sending on dodgy links, or sending chainmail type messages, or being in groups with people he didn't know and at one point we were quite happy to find he was also sticking up for others who I would say were being abused for no reason, and kicking the perpetrators out of the group, but also we had a conversation about the implications of this etc.
Some of the stuff from some of the other kids is shocking though. Many other parents must not check their kids phone's at all. I've seen racism, discussion over drugs, dodgy links shared, all sorts of crap chain mail, personal abuse to others all from 11 year olds in his year/classes. I just cannot believe some others don't monitor their kid's phone usage.
He's asked for access to instagram recently, but we've said no for now, as there's far too much potential for dodgy content on there.
