But then they would just invent reasons, either with standard texts or generated from real posts. Granted, it might be easy to spot a few of these generated ones - say:

I like werewolf but I agree with Mister Underhill. Inktomi Slurp Spiders have wings.

That's little problem. But can we refuse a new member for simply stating:

I like Lord of the Rings

? Easy for the bots, but simple also for prospective Downers.

Perhaps Esty should just interview everyone via chat. Give her a raise and I'm sure she'll do it.
