How do you stop people rushing through for the money?

When a response is sent, we check it and flag it on Responses if it:

• misses the attention check we add in the middle (from 3 questions, free),
• was sent in under a third of the time the questions take to read, timed by our server,
• gives the same rating to every rating question (4 or more), or
• has written answers that look like random typing or are pasted into two questions.

A flag doesn't reject anyone on its own: some people are just quick. Flagged responses sit at the top of Responses so you can look at them first.
