But you can't assume that HTML, CSS, and JS are written by the same
person, let alone all HTML, CSS, and JS in a whole site. They might
not even be written by the same team (if the concept of "team" applies
even), or people in the same company (if that applies).

This sounds like a recipe for trouble to me.


The 'net used to be run by smart people; now many sites are run by
idiots. So SAD... (Sites that do spam filtering on mails sent to the
abuse contact need to be cut off the net...)
