The thing is that not everyone have the same taste in things. This is a sim forum after all, and not a movie discussion forum. While you might think it's the greatest movie ever, others might not. A lot of teenagers hangs out on the forums (13+), as well as older people (30+++) and they're bound to have different tastes and opinions. The more people (particluarly creators) who are interested in it, the more likely it is that they get a response.
As for hotlinks, I'm guessing they linked you on to one of the "how not to hotlink" topics, so I won't bother with that.
Several sites, including Insim, have had their problems more or less recently. Insim came close to dying out, and probably would have, if it wasn't for the "mainstream tards", using your words. We've lost several members, unfortunately. Some might have moved on to other sites, othes might have lost interest in simming. That's just the way it is.
I'm guessing that your request would probably have more luck at GoS, but they've recently been out of business for quite a while, after having been millimeters from closing for good (an outside problem, the site is/was quite popular before the problems started). It's a more alternative site, with perhaps fewer mainstreamers. Maybe someone is interested in your request there. Might be worth a shot. The site is stll a bit unstable, though.
http://www.digitalperversion.net/gardenofshadows/index.php The thing is, a site is what the members make of it. Moderators can set a course, but it's ultimately the members who makes the decisions on what content you'll find, which in turn draws more members of the same type.
Also, people do requests in their spare time, and use whichever skills they have. Not everyone feels like taking up requests they're not really interested in having in their own games. Just be glad if someone does. I've posted many requests over the years, but only a few were answered and fullfilled. For the rest, I eventually had to figure out how to do it myself, if they were important enough to me.
And as for making sims, depending on how thorough you want them, it is fully possible to learn to make them properly. You don't even need other tools than the ones that already came with the game, unless you plan on making CC for them. You have no idea how free you'll start to feel when you're able to make at least some CC on your own. In the end it's time-saving, because you don't have to wait for it to be made, and it is fun (even addicting). You can't find creativity without people wanting to create.
And it is possible to be nerdy, geeky and a little mainstream at the same time. It's not that easy to follow today's community by digging yourself down into the past. I'm pretty sure that most of the things you consider not mainstream now were mainstream once upon a time. A little newsflash to you: Times change.
