Admin should also work harder to check suspicious user. I reported one already and got banned. Though I believe it is not my job to do so but I believe it was helpful to report if the admin and moderators were not able to catch one.
That's great. We should help the admin to report anything which is against the guidelines if we want that this site runs longer. I know it's not easy for the site admin to maintain the things but with the help of the members the work of the admin and moderators can be reduced.
