I've been mostly lurking and rarely posting on this board for a very long time, decided to change this and make a bit longer post

all kinds of serious input appreciated.
Short intro - I've been making designs (pay/tgp/free/avs) for a long time and I noticed that it's more profitable to make sites for myself than for clients (a small ongoing % is more than one time fee). Now I have well over a hundred BYOT/paysites, premiumAVS (now AEN) video/dvd sites spread around several networks, with 2-3 thousands of (free)hosted galleries. Over 90% of earnings that these sites make are actually siteowners' cut from other webmasters traffic. I am familiar with blogs/tgps, but I never had the time to actually sit down and make my own network and traffic source. In a few days I'm off for a vacation, and when I get back I'll start this project.
To make use of all those hosted galls, I'm planning to make a fake-tgp network (TGP rotator is now unavailable but there's a more powerful replacement script), I'll be buying some feeder traffic, gall spots for galleries hosted on those domains, the part I'm unsure about are the domains themselves. Is it ok & advisable to use expired adult domains, or is there a possibility of buying some blocked/blacklisted domains bringing "bad karma"? instead of some free traffic

is there another good list of expiring names except exxxpired.com ?
I also want to make a network of blogs (writers come pretty cheap nowadays), should I use a different set of domains, or can I simply put them in a /blog/ subdirectory? First I thought of making each blog a default index, and keeping the tgps in a /tgp/ folder, but that would drive dirty tgp traffic to blogs (404s and ppl who check out the index page). I'm not sure about mixing these two types of sites on same domains, and SE penalties). How would you organize this? Over time TGP network should be on autopilot so to say, and I'll work on blog updates. Depending on my remaining free time and tgp growth, I might open submissions for other wms later on (sites will be relatively narrow-niched), if visits grow to a number worthy of submitting to..
I know this won't grow and make 1000s over night and I don't expect it to, I just want to make a goal and get it done instead of crazy jumping from project to project for various clients

, and I want to make a better use of my sites because I believe there's a good potential in them. It's very late & I'm tired, sorry if I mentioned something twice and skipped something else

anyway - I'd like to hear opinions - is the general idea ok, am I missing something, what should I stay away from etc. Hopefully this thread will become a nice tutorial for everyone else who's out of focus.
