Keyword Stuffing still exists?

A local plumbing company seems to have a hold on the market. They have the #1 ranked spot for almost all town names in the area. They have a fairly big seo operation going on I think.

My question is, on each town/service page (aimed at keyword "town name plumber"). They have a massive list of keywords at the bottom of the page.

I thought Google hated this? How are they still dominating? Am I right in thinking that eventually they will be punished?

I dont think google will Punish them for that I have seen several website that have that below.
There is a wordpress plugin that does that automaticly!
You shoould take a look at the backlink profile of that website to get a bettter clue why he is ranking!
On page seo has become less about spamming keywords I dont think that even works or has effect on ranking.
I think its all about the backlinks
