Susheel,

This is not anti-competitive. It is PRO user. You've highlighted a major potential nuisance to our users. You've shown spammers how to get web pages into millions of users faces. (Okay, maybe they aren't that smart yet but they will soon likely figure it out.) I think we can safely assume that users will understand and appreciate the fact that we want to block spam.

No ill intentions on our part. We are just trying to do what's right and our users come first.

Thanks
