[Ladies, Need your help] Would you pay for an app that deleted shitty messages in your OKC account?

I'm interested in making an online app that will automatically delete all dumb messages like:

hey... How are you? Hey cute thang, lemme get yo digits! and a whole plethora of sexist comments.

This would filter out the idiots, and only the interesting/more thoughtful messages would be left behind.

I'm guessing the dumb messages would be marked as read, and the good messages left unread.

Would you guys be willing to pay for something like this? If so, how much?

Would you want a free trial first?
