Senior Member, Dayo_UK at WebmasterWorld posted a very interested thread named Ask Crawl Banned sites? The question posed was, does Ask crawl banned sites? If not, does Teoma bot (Ask's spider) activity suggest that Ask has removed the banned site from it's spam list?
Excellent set of questions. I emailed a contact at Ask to get some answers. And guess what, the answer is not black and white, what is with search. I will phrase the answer in my own words.
When a site is banned in Ask, they cease from crawling the site. However, Ask may crawl a banned site during an "experimental crawl," during a site's ban period. From my understanding, recent and consistent bot activity, may strongly suggest that a banned site, may possibly be reincluded in the next index update. You must be able to differentiate the "experimental" bot activity from the normal bot activity, which may be very hard to do.
