+      Bleach is an HTML sanitizing library that escapes or strips markup and

+      Bleach is intended for sanitizing text from untrusted sources. If you

-        setting rel attributes, even on links already in the text.
-
-        Bleach is intended for sanitizing text from untrusted sources. If you
