Many of you already know that Rabbi Nosson Slifkin's books have been banned by a list of rabbis that includes Dovid Feinstein and Yosef Shalom Elyashiv. Rabbi Slifkin's 'crime' seems to be his argument for the earth being more than 6,000 years old.
You can read about the ban here.
See the best satire on this (if I don't say so myself!) here.
