Ahem!

1) Disable the "Add portal member" permission for anonymous.

2) Do a CVS update.  As of 5 minutes ago, ActionsTool now checks for the
"Add portal member" permission before displaying the "Join" link.

Now, there are some customizations that aren't going to be this easy. 
But you can customize every bit of the CMF without touching the core
code and without creating a "hotfix" product.  You can subclass and
replace the tools instead.  I'm sure there's a document somewhere that
talks about that.
