My post has gone to Australia

[Lavatera]

I posted on here last week to say I shouted and swore at my 12 year old.
Reached 1,000 posts and over 3,000 people voted.
A mumsnet user very kindly sent me a DM to tell me that my post has been re-posted on Kidspot, an Australian website. Under the tween advice section. Sure enough, it's there. I never gave my permission for this! I had never even heard of this website. No-one has contacted me to ask my permission.
Is this allowed?
Once you post on mumsnet, can any website take your post without you knowing and use it for their website?!
I've emailed them, a few days ago, to tell them I do not want my post on their website and have told them to remove it, but I have not had any reply from them and my post is still showing, they're actually promoting my post on their front page for tweens.
I don't want my post on Kidspot!

I’m afraid you posted on a public forum. It’s fair game for newspapers etc. that’s how it works.

It’s the Internet, you can’t control it. You don’t own the content that you create, so post at your peril.

I thought it was a Royal Mail problem at first!
