Limit the maximum post comment length to something less spammy, such as 5000 characters.
Why would it be useful?
Someone posted the full script of the Bee Movie in post #1141822, and now that whole thing turns up in nearly every comment search. I've already had to scroll past it dozen times.
What part(s) of the site page(s) are affected?
Post comments, comment search
