That suggestion makes good sense to me.
I don't like this suggestion also.
Person who was accidently clicking ignore button would now be getting popups more often, and honestly that would annoy me much more than few ignored members.
Only good reason to have confirmation pop-up is when I am permanently deleting/changing something or closing my account.
Having to click confirm often would suck big time for 99.9% of forum members.
Would it be possible to create an option in the user's profile for this "pop-up" to appear or not?
Whoever activates the option would receive this alert. Those who preferred not to have an alert, continued without an alert.
I thought about this in order to please both sides, and perhaps to avoid creating so much complexity in this whole process. Although it would probably require recording more information in the database, which may not be recommended.
