Your comment consist of nothing that can be considered constructive or criticism, as many of told you before. Saying you don't see him on the server when you're on isn't criticism or constructive. Thinking he's not a bad guy is an impression you have of him and it doesn't say anything that the applicant should be improving on or avoiding.
Let's go over the definition of constructive shall we:
- adjective - having or intended to have a useful or beneficial purpose
So whether or not
you think it's useful or not doesn't matter. I posted my view on him which
might be useful or
might not be useful to
anybody else who is looking at the application.
My intention was to comment what I thought of the applicant, telling people that I couldn't see any bad issues with him myself. If a lot of people feel the same way then it helps to show whether this user is genuine or not.
The fact of the matter is just gave my honest opinion on him like everybody else does which is precisely what you are supposed to do on an admin application.
