It's unfortunate that you feel this way. I have always made my sims from stock sims in the game and am more than willing to prove myself if need be. I create for the joy, the challenge for myself to learn new things...not for downloads or ratings. Which is why I no longer post my creations on sims 3.
Every sim I create is modeled after an actual model...a real person. And I'm sorry but I'm uncertain what your sims look like as I have not downloaded a sim in years.
I almost feel as though I have been thrown into some sort of "war of the sims" just because of a site I joined. It's a game, it's supposed to be for fun...or at least that has always been my intent which is why I usually steal clear of the drama.
I didn't join this site to "sneak around" or do whatever you have imagined. I simply enjoy playing the sims, and every now and then see a person who looks interesting to me so I try to create them as a sim.
Anyway, I hold no ill feelings and am uncertain why you have them towards me. As I stated above, the fun for me is the actual creating from stock. I have no reason to copy nor would I ever and if you wish I can take photos of my process from start to finish just to clear the air.
