Important question for link list owners

[CrazySy]

A good day to you all

As some of you may know, I build freesites for a few other webmasters and some programs but there was rather a big problem brought to my attention a few days ago by one of my clients regarding his freesites being declined. He was told that his sites are similar to mine and that's why they chose to decline the sites and removing some that were already listed. (there is only one link list that I am aware of and it happens to be one of the most established ones)

So here is my question for you guys/girls:

Where do we draw a line as far as rules goes? I don't use the same templates and apparently the sites can't even be similar, so what is next? I can use only one color background per month? LOL

I am not trying to be bitchy and rude but what do some link list owners want? I mean it seems like you can't make them happy regardless of what you do. I do underestand the use of same templates but "Similarity" also gets you declined? Not that you have much to work with, there are only 4 pages with limited content and limited ways to design a site.

I'd appreciate your feedback so I can continue my work the proper way to benifit all parties involved.
