There is a tweet being retweeted heavily within the German Twitter community right now which roughly translates as
“BEWARE Nazi-pigs on Twitter! @Heil_Hitler_88 Please block so that the account gets deleted. #nazi #block #rt Please!” (original).
Now, if Twitter had servers in Germany an account like @Heil_Hitler_88 (we’re not linking BTW) would be illegal and would be deleted right away.
