Since I think just about everyone uses craigslists to market their listing I was wondering what everyone thought of Craigslist's proposal regarding html?

Basically what they are saying is:
"Unfortunately, much of the HTML in postings these days is used by spammers for harmful purposes, such as cloaking spam links, embedding false keywords, and overriding the flagging system."

Interestingly there are a number of comments on the forum aimed directly at the postlets ads. I think postlets is a great service but, not to fault postlets but, I have to agree many have abused the fact that postlets ads are aren't seen as duplicate content, resulting in many abusing the rules and overposting.

What are your thoughts?
