I would be VERY careful interlinking your own web sets... especially 100 of them. If A links to B, B links to C, C links to D, D links to E, E links to F, F links to G, G links back to A... for example, Google has gotten very good at detecting such linking schemes... which fall into the "unnatural" category. If you're still doing link building with forum signatures, article submission, directory submission, etc. this too raises red flags and are all considered "unnatural" especially if done in mass.
