I just encountered a post that was essentially a duplicate question posted as an answer to the question of which it is a duplicate. The question was US to UK visa or no visa for multiple visits.
The answer was deleted by moderator RoflcoptrException.
I don't disagree with deleting the answer, but I do wish the moderator could have posted a comment. Although the user posting the question is a new unregistered user of the sort who often never returns to the site, a gentle word of explanation would certainly increase the possibility that she would return to the site and perhaps become a valued member of the community.
Should moderators be deleting such answers without comment?
