Mine can't hand numbers in a title, so I have to edit
18 and Horny to be
Eighteen and Horny. Well, the main listing part doesn't mind numbers, but I have a lot trickery employed on other pages - that's what falls apart when it's faced with numbers. I certainly don't expect my submitters to know that and don't expect them to modify their titles just for my site.
But to answer your question
, my script can eat apostrophes all day long and never complain. When I see a title without an apostrophe, like
Jizz in Jennas Asshole, I assume it's just another webmaster who hasn't fully embraced the possessive form.
