Digitalocean is based in the United States, so if you host your instance there, you will have to follow the laws of that country to some degree (at least if the instance gets big enough for someone to notice). It will probably be similar if your instance is hosted in another country, and I dont think there is any country that is clearly neutral.

So my suggestion is to think about which countries your instance would mainly criticize, and then host in a “hostile” country. For example, if you want to criticize the United States, host in Russia or China as their governments wont care about that. Or vice versa.

Then the United Nations are holocaust deniers. Fact is that no international court or UN organ has even investigated the alleged genocide. Innocent until proven guilty.

Here are some interesting facts related to this topic:

• These claims are promoted mainly by the US government and US media
• The USA has invaded many Muslim countries over the last decades, killing millions of innocent civilians
• Most Muslim countries support China’s Uighur policies, western nations oppose them
• According to Biden, USA is in “extreme competition” with China
• Xinjiang is a vital part of China’s “Belt and Road” infrastructure project, because it provides the shortest path to Europe

Edit: One more thing, here is a list of terrorist attacks in Xinjiang. Note how there were no more major attacks after the vocational training program was established.

Or you can just use Library Genesis, they have millions of books.
