In answer to the question about LLs that cheat and how to find them - there is a small issue in that while most will blacklist a LL for stealing/copying somebodies LL recips (like has happened in the past for Hoes and Cleos and a few others) there are link list owners out there that dont care about that and will continue to list free sites using those stolen recips or other copyright infringements etc.
I dont pretend to be the Link List cop and making a central database would just be asking for trouble in my opinion as out of the hundreds of link lists out there that would use it - I can guarantee based on posts Ive seen here that there are link lists owners that would list anything as long as it has a recip to their site and has 4 pages
- all they care about is having the recips for their misconceptions of search engine positioning LOL
