Not wise. Those settings must be loaded and parsed on every page load of your forum. With a handful of entries it's no big deal, but leave that on long enough and hundreds of IPs will turn into thousands, and then tens of thousands... Eventually you will exhaust your PHP memory limit or MySQL packet limit- but well before then you'll see noticeable slowdown of your site.

The vBulletin Ban IP box, or any mod settings is not designed to hold thousands of entries.

The best solution would be to regularly output a text file of IP addresses and have some way to block them on the server level- before vBulletin or even htaccess is accessed.
