I know what defamations means and I didn't say you had defamed them. I was commenting on what could constitute a breach of the law in the context of posting videos to the net. Hence the words "might" and "depending on what else you say".
Sandy - I know littering is, but feeding foxes per se isn't.
My point is that the fact that something isn't illegal doesn't make it potentially objectionable to others - whether you are talking about feeding foxes (which, personally, I find a pain as I'm sick of foxes), getting annoyed at being filmed without your permission (which I would also probably get annoyed about) or whether posting videos of your confrontations with your neighbours to the internet including identifying their address (which I can't say I'd be that thrilled about either).
There are less aggressive ways to deal with your neighbours.
