What advertisers allow the publisher to resuse their earnings to buy advertising?

[Chris]

All, as far as I know. I've never heard of an advertiser to refuse to take your money.

If you mean automatically, I haven't heard of much, but I don't pay attention to that as it isn't a feature I'm interested in. As I recall searchfeed did though.
