There seem to be reports of users having a glitch-like problem with their score, without having completed any survey in the meantime when this happened (to assume that they broke a rule).
The issue was that these people's scores were either reset to 100, which is the default score, while they had much higher scores even close to 2000, while others dropped to a negative score.
When scores drop, these users are not eligible for high-score surveys or any surveys at all if it drops low enough. Therefore they are unable to earn.
Site admins have been notified via e-mail by the afflicted users, but as of now we don't have any answer as to whether it's glitch, old accounts gone expired or random resets.
If you have an account with them, check your score.
