In all seriousness, this is the biggest reason that I don't use Twitch. I know the risk is low, but all it takes is a single troll somewhere in the world to find my CV or a WHOIS record.
You're not at risk of getting SWAT'ed in Germany, though.
My (UK) ISP puts my full name and address, home phone, email etc. in my /64 v6 allocation, and I think also for the v4 address. It's not optional, but then again I'm not worried about being randomly shot by SWAT.
