Why doesn't google allow 'google hints' for all accounts?

Why doesn't google allow 'google hints' for all adsense accounts? I have seen this on some very big sites, but when I try to use 'google hints' in my adsense code, it does not work.

So why the double standards?

I have seen umpty number of cases where the adsense bot does not have a clue as to what ads to display. In many cases it displays public service ads when the inventory does have many related ads to show.

I understand people can use 'google hints' to manipulate the ads but how does that make a difference as far as the clicks are legitimate?

If you are not sure what google hints is, it is a variant that allows you to tell google bot what the page is all about so it can display related ads. For instance, google hints="keyword"

I agree, would be nice! I guess they fear too many people would try to game the system and it's not worth the trouble.

Too many people would stuff high-paying keywords in their hints. This would lead to so much abuse, that neither advertisers nor publishers would gain from it.

How about allowing people to non-bold that ads? Will that help people game the system too?

Or is there a system to non-bold the ads that I am not aware of?
