I worked customer service for "a" major MMO for a while. People who got asked if they were robots were generally behaving like robots: using macros (pre-written responses) to respond to questions even when the answer didn't properly fit, sending responses (even proper responses) to questions faster than people generally type, or abusing the auto-name-fill-in shortcut to fill in the character name in every sentence.

In short, there's very likely to be an actual problem when your customers ask if you're a robot ... not a "cute" problem like you were too quick to answer their initial request.
