==================
There is a lot of information in this thread. Some of it mis-informed. Some of it good.
I think some of the posters see the problem, and some don't. Their defence being that lots of pages are indexed in Google, so there can't be a problem. But even Google thinks there is a problem. Quote from,

That's what UBB has. Items linked via multiple distinct URLs.
It problem is not with being indexed. It is about being efficiently indexed and fully indexed.
