Ask HN: Snip.ly security issues

The Show HN for Snip.ly was on the front page for a few hours and it stirred up a big controversy (penalized once it hit 40 comments). Now I'd like to specifically Ask HN for solutions as opposed to feedback on the product.

Summary: http://Snip.ly is a link shortener that lets you embed messages into any website.

Side A: Powerful tool for extending your brand, providing commentary, and provide relevant resources.

Side B: Potential for spam, malicious use, and phishing.

The HN community provided some great ideas, such as requiring a certain follower:following ratio to register, automatically blacklisting malicious links, etc.

Please share your suggestions!
