Keyword stuffing eBay titles

I have never done any keyword stuffing (like listing a Ralph Lauren tshirt and just adding the words coach, gucci, nautica, etc at the end) to get more visibility to my auctions via eBay search. For those who do it, is it worth it? Did you notice a significant increase in views? Does eBay give you trouble for it? I'm tempted to start doing it, but obviously don't want to lose my account. Thanks!

Your listings or listings will get taken down eventually so it's not worth it in the long run. Usually it would be from being reported so depends on how much competition there is.
