Stopping necrospam

Moot needs to implement the Anti-Necro fix from https://dis.4chan.org/read/prog/1378179410
You can't stop it with captcha. Its either bump age limits or reduced bump power.
Plus fix the new thread form(i currently can use it via extension script).

So obviously Spammer-chan is butt-frustrated that captchas have been implemented so he's necro-bumping 1000 post threads as a protest.
Now how do we fix this?
Easy, we delete all threads when they reach 1000 posts :3

This is a terrible idea. I suggest we just keep changing /prog/ until Spammer-chan commits sudoku out of despair
