In this recent post, one user suggested to extend the grace period for account deletion, given that they felt those points were valuable or could be used in some way.
Although the user has now dropped the idea of reusing points, I think the grace period should be extended for more than 24 hours as of now. According to this post, when you press the delete button, if you do not reactivate your account, an automatic script will delete it.
Given that other sites have longer grace periods, for example Khan Academy with 7 days, Google at 30 days, and Microsoft at 60 days (!), the grace period at Math SE is insufficient as users should be given more time to think about their decision.
My impression is that there are some 'nudges' that are put in place by the system to encourage good behaviour: for example, a dialog box will pop up when you try to delete your own question that already has answers. Given this, I think it is in the community's best interest to extend the grace period, so that the results of an impulsive deletion will not become permanent. This is in the spirit of SE policy, and has been echoed by Shog9 in this post (as he wrote, 'So, y'know, we do try to make sure that's what you really want first.')
In addition, although all the posts of a deleted user are still kept on the site, all of the votes will be nullified (edit: as Martin Sleizak commented, this does not seem to be the case). Although the effect will not be that large for posts with many votes, for a post with few views and few votes, the vote of that deleted user provides valuable information on if the question is good or not. This information should not disappear unless the user of that account really wants it to happen.
So what do you think about this? Do you support extending the grace period for account deletion to 7 days, or even more?
