Maybe not. If you claim to be living in an active warzone and go missing who would look for you?

Flee to Western Europe under an assumed identity, get taken in as a refugee?

Assuming you can fluently speak in a language expected of a refugee and are not from a country that has your prints on file...

Before he spent some time in Transnistria as well, which is also a weird choice.

It's an excellent choice IMO from his perspective. They grant citizenship after 1 year with not a lot of questions and have a cash economy. And they don't extradite to the US.

They'll also not above confiscating your cash and killing you if its suits them. Or (before the war) they wouldn't think twice to send you to Russia to be used as a bargaining chip.

Weev is effectively banned from the banking system. The list of places with enough infrastructure to survive as a hacker, without foreign citizenship and in a cash/crypto economy with no extradition treaty is thin. I'm sure Transnistria might do that but apparently it wasn't worth their time to kill him. Seems better than North Korea, Iran, or the bush of Africa.
