I have questions:
-
Does the government just "not care" or is piracy specifically legal because there aren't local laws against it?
-
While you say they don't care right now, do you think there is a possibility that they might care in the future? Because governments often capture lots of information on their citizens with the knowledge that they can then target people that they dislike. Piracy is one of many things governments can use against a person if they really dislike them or what they're doing.
If it's explicitly not illegal and won't be in the near future, I wouldn't be too worried.
However, it might be a good idea to avoid public trackers anyway and focus on slowly growing a good reputation on private trackers. That might take some time, especially if you have a slow connection, which is quite possible in a country that doesn't care about this sort of thing.
You won't necessarily need a VPN for a private tracker, but it gives you a small amount of protection since at least the members of a private tracker are a (supposedly) vetted, trusted community instead of just any random person grabbing your IP.
