 Try to put something like this into a post (with unfiltered_html enabled):

 {{{
 <test:something>
 garbage
 </test:something>
 }}}

 If the balance tags option is enabled, it will mangle this content into
 this:
 {{{
 <test :something>
 garbage
 </test>
 }}}

 Reason: Balance tags doesn't understand that colons can be part of tag
 names.

 This makes using things like XFBML (part of Facebook Connect) in posts
 very difficult.
