Attempted spam reduction and cleanup

* Added DNS blacklisting
* Sorted misc stuff at the bottom out into sections
* Removed things that were all declared later
* Removed use of $bmServerBase, I don't think any of us use it anymore
* Removed some pointless comments
* Fixed some whitespace issues (tabs, unnessacary vertical aligning of expressions)
