From what I have heard at first you should just set up a page with original content and not overly promotional. No links and no affiliate banners, etc. Leave it until you have a rating of 75 or over once this happens your page with links will become do follow and you can point them at your site, etc.
sorry but this is not always the way to do it. If I would always have waited to put on my aff links., I would have missed out on all the cash to be made on the way to the top,. hell I got sites with one person visit a day and they click the banner and get me a 16 dollar lead.
So did you put your affiliate link on the page the very first day? When I was doing my first Hub it was a pain in the ass with their, "your page is too overly promotional and will not be published".
its nofollow
everything is nofollow (twitter etc ) , but you can make it do-follow ... just write quality n etc, if u get a good amount of good votes... it will be do-follow
Well I'm watching SEO videos and they said that Hubpages are really good if your site is do-follow (hub i mean) , and to make it do-follow, u have to write quality articles, and not make your fellow visitors think you are doing this for ranking yourself better(advertising etc)
