Well that would seem better however each site is different in the type of spam received, I may in fact find time to do that however it's still simply based on my opinion and experience using said modifications. I've found over the years that some mods work well on most sites then on others not well at all so you must truly cater to your site. I will say that the three primary ones in the first list marked w/ *'s (indicating they should not be used together) are some of the most used on vBulletin sites, others have been released since the time of this articles writing as well, I'll include them in the list when I have a few spare minutes.
