Government don't have to "force" Bitcointalk to leak user's IP. They just send subpoenas to Admin (Theymos) asking for all the details of the account(s) they're interested in. I believe that's applicable only for ongoing investigations, where the charges have been pressed, not a routine checks, but not sure on that.
In your case, in practice, your local authorities would have to know that you are resident of the country and if they wanted to go after you, they would have to request their US counterparts to get your details from Theymos. That is very unlikely to happen unless you're a big fish.
What I would be more concerned about, is your local law enforcement authorities asking your local Internet Service Providers for the details of all the frequent visitors of BTC/crypto related websites.
Invest in VPN.
Damn,I haven't thought of governments asking ISPs to check people activities.
The problem with VPNs is that they are also companies and nothing guarantee that they also won't leak my IP address etc...I think tor is the best to go since there is a concrete proof that with tor you are untraceable (dark/deep web) but yet,BitcoinTalk is having issues with accepting tor dunno if they changed that though.
Anyway thanks for the replies guys.Let me know if you have more infos.I'll try to figure it out on my part.
Only administrators can see his IP address unless the data is compromised yes. However, there are some "tricks" if someone wants your IP, but if you are targeted and someone really wants your IP, you just need to not make yourself a target...
If you are really concerned with your IP, buy a VPS, make your own VPN. You need maybe 30 minutes and can find some cheap deal on LowEndBox for $15 per year
I don't trust VPNs that much to be honest but thanks for the suggestion VPN better than nothing
