Would linking low PR sites (PR1-4) with the same root domain hurt or help an established website.

This is one of those that I am not sure has an exact answer: If per your example the urls beyond this are all linking to ABC123.com and are all the same xyz123/bettys, /susies, etc. I do not think initially it would hurt. I do believe at some point say for clarities sake at 100 there will be no additional benefit. (The root domain is not changing) Frankly, I doubt it would add much at all to a strong and established site.

If each of the urls is a site one thing that will draw attention will be whether or not they are on the same IP or C block. So if you have 1000 low PA sites linking to your strong site and the IP addresses are all the same or the C block is all the same I think you could potentially be causing yourself a problem. How big? I don't know.

Best of luck.
