Once, on Second Life back in 2008. But I've since found ways to legally change my router address without having to worry about breaking the law. And of course, I've moved houses and got different internet since then... Well more like, my old house was cooked to bajesus and back, and i can only get century link where i am now.
I've also gotten banned from the MLP: FiM wiki chat room for... get this! talking about engrish.
I wasn't even trying to be mean, i think it's actually adorable how other people talk when they try to speak english.
But anyways, some guy got insanely offended and told me to go **** myself. (Also happened before my house was deep fried)
And i've also had my share of warnings on ROBLOX.
