@alexhost how about .com domains? I have an anime website and it's a .com
To be honest with you, every domain can be seized or takedown, some domains are very hard to be seized, others take sometime, others are easy.
.com is managed by Verisign an company from US. Your domain can be seized easily, since it is under US Control.
But that doesn't mean you will be seized or not, if your website will be bigger like Piratebay, 1337x and others that can make you in trouble. Or if your website are bigger in your country, is a little dangerous.
.to is not secured anymore, still be fine to slowly the process, but now they have subpoena to know the owner behind .to.
Domains that are still good are: .ru , .su, .cr , .is, .sc, .ch, .se
If you want something like .com, is best you use .org and use EasyDNS (look at piratebay.org registar is EasyDNS and requires court order from Canada to takedown) is for that reason why TPB (ThePirateBay) still with .org domain.
But the registar can agree and seize the .org, it depend of registar.
