Xrumer or Drip feed blast?

[afranklin]

Wondering what the pro's thoughts are on using Xrumer or drip feed blast on building links to Web 2.0 properties to rank in the SERP's?

I know it could be dangerous to spam your site with these but do you see any harm in using them on web 2.0 properties like YouTube to get video's or other content to rank high?

I've had success using DFB on pages that link to my sites.  I have always shied away from blasting anything like this to my main sites.
