I would like to see NoFollow links. And as far as I can tell, Flarum has almost none.

Use "nofollow" tags
Together with Yahoo! and MSN, Google introduced the "nofollow" HTML microformat several years ago, and the attribute has been widely adopted. Any link with the rel="nofollow" attribute will not be used to calculate PageRank or determine the relevancy of your pages for a user query. For example, if a spammer includes a link in your comments like this:
<a href="url">This is a nice site!</a>
it will get converted to:
<a href="url" rel="nofollow">This is a nice site! </a>
This new link will not be taken into account when calculating PageRank. This won't prevent spam, but it will avoid problems with passing PageRank and deter spammers from targeting your site. By default, many blogging sites (such as Blogger) automatically add this attribute to any posted comments.
I like the simplicity of this detterence.
