Not a lot of people know that.

You've seen these things, I'm sure. Type in daiFin,10 and it accepts it.

What you might not realise is that somebody is actually using them to get humans to read what's in the photograph for them. I'm not sure what this task is part of, but somebody somewhere wants this information. Typing 10 works, but so does typing anything else at all. I always type penis. It always works.

Have fun.
