A moderator is asking a question like "How to detect a program in Windows 10, that uses Process Hollowing?", but if there are answers to his/her post is he/she able to delete answers from the question the moderator himselve posted?
This fact would not be useful because the person is asking the question, so he/she is the person who ask for help and thus uses the vote/downvote functionality without extra candies especially this one.
