Re: Security and Nyaa!
Seeders are more likely to get "contacted", as they are sharing and fall under hard fist of law.
P2P (like torrent) works in such way, that anyone downloading is also sharing at the same time.
Grabbing info on all people that were torrenting something? *snaps fingers*, like that and done, easy.
So yeah, if you want to feel safe - get vpn (though, in some cases it may just be cheaper to get those games at sale). Otherwise assume that you are not safe, not at all.
Technically, because in reality it's easier to go for bigger fish (top seeders and people making those torrents). From time to time Japanese devs will do a strike, take or try taking few major seeders, then wait and repeat.
Other, cheaper solution would be to just keep your drives encrypted, so in case of anything they can't do shit, which is checking your computer. Well, at least where I live, I don't need to provide password/key so they can't get into my files and can't prove shit. Depends on country, you have to dig on web and check yours.
Go on google, search "safe torrenting", learn something and decrease chance of getting caught. It's not that complicated and in most cases - faster and done in step-by-step guide.
And no, I don't support piracy. If you like something, support devs.
But I also don't like when people run around blindly doing something, so asking a question is a good start, getting proper knowledge on the matter is always better.
