Nothing judgemental here... just trying to narrow down the problem and see where Google is on this....
- Does each site have a strong, independent backlink profile?
- Do the sites have link sources in common?
- Do the interlinks supply a substantial portion of the target site's link juice?
- Do the links contain targeted anchor text?
- Do the domains share common or related hosting?
