The goal is to give customers tools they can use responsibly, and allow them exercise judgement. This is obviously the leading edge and we thought long and hard before enabling the functionality. One idea we have towards making visitors more comfortable with this would be to create a notification that enables visitors to see that what they're typing can be seen? Hopefully customer feedback helps us figure out which direction to go here.

EDIT: After getting feedback from some customers, we're building in an optout so that users

a. know that what they're typing can be seen, and b. can opt out of their typing being seen at all.
