In-Game Parser.

[Viridiana]

Zero holes, people will try and bend and twist things to make themselves look like parser's are good for those types of things.

You: I don't want people telling me how to play my job. You don't pay my sub fees!
Me: I'll just follow you around not doing any damage. You don't pay my sub fees!
Qi: That's taking it to an illogical extreme.
Me: It's me taking it to an extreme to point out that not paying sub fees is no justification for wasting someone's time.
You: What does this have to do with parsing?

Answer: It has everything to do with wasting people's time.
