Avoiding Akismet with Fast Poster in Scrapebox

When fast posting through Scrapebox, do you guys do anything specific to avoid being targeted by Akismet? I mean... it comes pre-installed with WordPress so most if not all blogs must have it.

Either way, I heard that if you blast the same domain too fast (let's say to a 20k AA list), that domain name gets flagged and all comments on blogs that have Akismet enabled are marked as spam (because that domain is marked as spam). How can we avoid this but still use the fast poster? How many posts trigger Akismet? Is there a way to set a delay on the fast poster?

Come on, someone must have some sort of input on this?

Spin your comments and use shorturl services.

Why would you blast a domain? These methods don't work anymore, try a slower approach.
