Copy pasting my post from your topic on general feedback as support :

I wouldn't mind one every 2-3 years not cumulative. I mean, at the end of the day deleting a character is an active choice and there is no reason why they would have to deal with it more than one time.

Then again bad things happen you could have been depressed or someone got his hand on your account and delete you character for the lulz because some peoples can be absolute morons.
