Thanks. Well, asking this actually wanted to help a friend of mine ranking his photo course biz to page 1(currently page 3). As you know photography website does not have much content really on the website. If in another approach, lets say I link from PBNs to my site and then 301 redirect to my friend's site, do you think his site will get penalty too?
A site with a photo course is hardly a local business site. If his site were a local photographers site that includes a course, that would be different.
There is no search term related to courses that I can think of that will trigger the local algorithm except driver training, and maybe a handgun owners course.
If his site is a course, treat it like a global IM entity.
If a photo site does not have much written content, the person building the site does not know what they are doing.
The problem with most photography sites is that they are in flash. Beautiful but invisible.
Regarding your question:
If you point your PBN's at anything and then link that anything to his site, it will pass both good and bad.
I do not know if a redirect would kill the destination site in case a PBN were spotted, my gut tells me that it would because after all, you have control of that site.
If you used a buffer site and simply linked to your site, then the penalty (it would seem) would hit the buffer site , and travel down the link.
You have a certain amount of reasonable deniability regarding your ownership of the buffer.
