I have a link list and I list free hosted sites, but only if they have my sponsor codes on every ad

I also submit free sites and galleries, but I either use my own content, or download content from a sponsor and use theirs, either way, the design is mine and the bandwidth is mine.
Why would I, as link list or TGP owner, list a free hosted site or gallery designed by the sponsor, with someone else's sponsor code, when I could easily just have my own code in there
And as a submitter, why would I expect anyone else to list a free hosted site with my code, and not their's?
This business requires some work, and the rules are there for solid economic reasons.
