My take on this is that Adsense does not link directly to your site anyway, it has to go through Google so it can be tracked. This means the worry of links from a bad neighbourhood by just being an advertiser is not real.

However there is nothing to stop scraper sites linking to you as the result of you listing well for any term on any engine (see the Yahoo API explosion) or by detecting who is advertising on phrases. I'd say it's easier to grab yahoo results (which are likely to give a good set of outbound links) than most other methods so scrapers are likely to do that rather than bother with advertisisers.

The final thing mentioned was the snippets, well once a scraper has your url as a source to steal from (and assuming the stolen info is bringing them traffic) it's not likely that quitting an advertising campaign is going to make them stop using your content.

I'd say this is a huge annoyance but cannot be solved by stopping your advertising, that will just cost you money (assuming you have a positive ROI)
