Wordpress and Hubpages ban people all the time if they think the blogs and hubs are being used for SEO purposes, especially new accounts.
If you make a bunch of "Personal" seeming hubs and blogs that talk about what you had for lunch, your new Camaro, or how much you hate the lottery with no outgoing links, blast the Christ out of them with SB, Xrumer, and a nuclear missile - you probably won't get banned and if you do, it's more than likely because of your content still.
They are close to the two bitchiest WEB 2.0 places out there, if not the 2 most bitchy period.
Anyways, blogger - gather - webspawner - livejournal....
