This site has the feature of voting for undelete but this feature can not be used:
I remember previously deleted answers could be voted for undelete. but recently this is not possible when an answer is deleted by a mod:
What is the reason for this change and impossibility of voting for undelete?
Is not it possible that decision of a mod about deleting an answer be wrong?
Why it should not be possible to vote for undelete?
Is not it a kind of dictatorship that users can not vote against decision of a mod?
This is a community site and users should have the role in moderation of site by using their votes.
Also if this feature does not work so why it is there at all?
