The markdown filter used by the forum does not set a rel="nofollow"
attribute on user links. This is fine for a small internal forum, but if
opened up to the world it allows spammers to increase their page rank in
search engines by posting links to their sites.

I personally replaced markdown by urlize and linebreaks, because it's
easier to understand by most users. Urlize does add this attribute by default.
