Actually I think uploading all the themes here is a great idea, as I'm sure the few people who stumble upon this old thread is because they are looking for the theme files... I think I have a really dated backup version of the site I can run temporarily, if you want me to get it up give me a PM and ill send you the IP/URL. Just warning you its a nightmare website if your trying to download every single file, also one last note I'm 90% positive that 3dsthemes.com did in fact die because of 3dsthem.es, rather it could have been just competition and some random events that I'm correlating, for example the hack might have not been them, but I find it weird that after the hack a brand new theme website pops up
All in all I think its just really sad, I had huge ideas for the site but it died way to early for them to be implemented. I think that alone is why I'm so upset about the entire thing.
