With the new deletion request system, users are given countdown text for a 24 hour period following their account deletion request to reconsider that request. This is a good feature.
This account is scheduled to be deleted in 19 hours. To cancel deletion, click here.
There are also requirements in place that users who meet certain thresholds (generally high-reputation users), must have their account reviewed by a CM before it will be removed. This is understandable. Unfortunately, because our CMs are busy people, this doesn't always occur within the 24 hours of the countdown. These users then get confused that their account should have been deleted but was not.
Please add a notice to the countdown text on their profile page for users who meet this limit.
Your account meets a threshold that requires manual review by a community manager before being deleted. This review may take longer than 24 hours but will be done as soon as possible.
Optional, "Thank you for your patience." or something like that.
Additionally, it seems that the count down restarts from 24 hours after the first 24 is over. It would also be worth noting in the message that, if the review is done after the initial 24 hour period, they will still have until the end of the new count down before their account is removed (if that's the case) or if the account will be removed immediately upon review, let them know that, too.
