That's what I call a fake TGP and it's absolutely nuts to maintain one manually (no offense).
If a fake TGP (basically a TGP loaded with sponsor sites not open for submission) is what you want, get a script such as
TGP Rotator. I have no experience with it myself, but I hear good things about it.
I don't think it would be a good idea to submit galleries with a recip to a fake TGP on it. Those you submit to want to be grouped with "real" sites.
