Well, at least you said something of substance, even if it's a little incorrect, in my eyes. Molten WoW has been up for 5 years for two reasons; 1) few people know about it (relatively speaking) and, 2) due to #1, not many people talk about it, let alone media channels (YouTubers, gaming sites, etc). Same goes for Dalaran-WoW. So few people there that there's no buzz. That helps it stay under the radar. This is the same reason that so many garage bands and niche DJs are so good. They've not been tainted by the general public. Plus, Molten WoW, from what my friends have told me, was utter shite. Buggy, hackers, and poor performance. I never played there, true, but that's largely why I didn't.
Nostalrius was shut down because they became huge. Popular. More people played there than almost all of the other "big" private servers combined. Blizz can't let something that is growing so large exist. Just having it there makes it grow larger and larger. If Blizz is hearing about it, Blizz is going to stop it. They HAVE to, in order to keep their IP intact. Law states that they must vigorously defend their IP, so they will and they do.
You said servers don't have to comply with c&d letters. You said Nost didn't have to, but they chose to. You're only technically correct. If you don't comply with c&d letters, you may face consequences. Nothing out there is stopping you from robbing a bank, but the law says you're not allowed. If you do, you will be hunted down and prosecuted.

As for your other comments, my original post was most certainly not a mistake. PErhaps I could've chosen to use better verbiage, but I fully intended to type what I typed. Sound mind and body. Secondly, nowhere on this website have I ever called anyone an idiot. I expressed my views and I was received with insults. I find it interesting that you see me as the aggressor there. Last, when I said, "...many months," I was talking about nearly a year. 10 months, or so.
