I've noticed MSN sometimes uses Mozilla/4.* plus one or two ISP bots like StalkStalk and a couple of educational institutions.
Other than that the rest of its' users seem to be bad news.
Does anyone know of any other reasons not to block 'Mozilla/4.* (Compatible' please, perhaps to add as exclusions?
