I see a lot of it Rosemary. You'd think it would be penalised but it actually appears to work quite well for some. I see some agencies with stacks of keywords in the footer, in fairness, generally they do link to landing pages with plenty of good content and they are getting results.

I think that having a few linking to high quality pages is something that works quite well. Having loads linking to poor quality pages is not good and also is rubbish from a UX perspective.
