10 year old Ds - Internet and lies

[movingonishard]

I've had various issues with my ds(now10) re the Internet - is googling things he shouldn't, setting up an Instagram account, etc. I had all this out with him a few months ago and I thought he'd told me everything he'd done that he knew he shouldn't. This all happens when he's at his dad's so I have little control over it.
Today I discovered he also set up a Twitter account last year( he didn't tell me about this when he told me about Instagram, etc). A positive is that he hasn't used it since we talked about it but am just so shocked by some of the people following him. I've reported the account to Twitter to get it cancelled as I'm unable to do it as he's forgotten his password.
We've had other issues with lying and sneakiness over the last year but I really thought I'd got through to him. I hate not being able to trust my boy. He's wanting to start walking home from school alone soon and therefore I feel he should have a mobile (very basic not a smart phone) but I'm so worried he won't be honest with me.
His dad ipand I split up partly due to his dad continually lying and I'm worried my boy is following his dad's behaviour. I'm even thinking I should ask my go for counselling for him to see if it helps. Any comments gratefully receivedsmile

Have you spoken to your ex about it?
Would he support you in this as well?
Tell your ds some of the horror stories about children meeting people who weren't who they said they were.
I've done that with almost 10 year old dd and she was horrified.

I have but unfortunately he doesn't share my views and even told him it was ok to use Instagram but to keep it a secret from me :(
