Tap the popup and carry on.
Don't tap the popup and you get flagged. Possibly some sort of "pause" feature for xp only. (No abuse like somehow protecting the character in a bubble, so mobs/players can still attack like normal.) Then you could have some sort of second counter. If the second counter reaches ___ time you're in trouble. If you exit that timer your info is still saved, and if you get enough of them in close proximity to each other that's another issue.
Also, I only throw things out and hope something sticks. Sometimes the "c" turns a bit and something stinks instead...
