Blogs that use other people's content

[Ms Naughty]

OK... this thread might belong in the linklist section but it's also a bit of a broad topic.

I had a submission to my 4women linklist of a Blogspot blog that primarily featured images, although there were also comments and stories in it.

The blogger had not included any links to say where the photos had come from, so I didn't know if they had been "harvested" from other sites or if they were licensed to the blogger.

An awful lot of sex blogs on the net use other people's photos, but they don't hotlink them, and they'll include a link to where the pic came from.

I recently got some nice traffic from ErosBlog because it linked to one of my sites... and it used one photo from the gallery to do so.

Where do we stand when it comes to this practise? Do we want to stop the unauthorised use of pics like this or do we tolerate it because it brings traffic?

And should linklists (or our own blogs) link to blogs that do it?
