I don't know why Bing allows tons of spam in their webmaster forums. It is really really annoying. All this spam makes the forums completely useless. A few days ago I asked a question about an algo update and it got buried in spam posts.
They allow signatures and people spam like mad with comments like "nice post + signature". They even allow to embed videos.
Have a look into this Bing indexing/ranking discussion:
I could go on with thousands of spam posts ...
My suggestion: remove signatures, disallow outbound links + disallow code embedding OR delete the spam manually
I hope Bill G. won't visit Bing Webmaster Forums, he will get a heart attack ;) But if he loves movies from India he can watch some nice movies there ;) Enjoy!
