The BBC employ staff to write articles for their website.

The articles are written to attract readers to the BBC website - not to attract them elsewhere.

These articles are copyrighted - and the Beeb are clamping down on it being stolen.

Someone comes along, and without giving it a second thought, copies and pastes it into a thread in here - one thread in particular was jammed packed full of copyrighted articles from BBC.
These threads are in turned picked up by Google - and every chance that someone from the Beeb with find this.
If this sort of thing continues, then eventually I can see large lawsuits flying around - and Ebid dont wanna be on the end of one of them for allowing such posts.

Then people throw their toys of the pram when these threads are deleted.

I, for one, am not surprised that ebid are doing the correct thing and deleting them before such lawsuits happen.
