If an admin is going to delete your post, an automated message is going to send directly to your 'my messages' and that means your post is not relevant or not good.
So before you are going to post make sure that you are going to post related to the topic and of course you are not going to post NSFW.
May na delete na kasi sa akin yung sa twitter exchange follower. Hehehe
That is a natural way of a moderator to filter the post here in forum so that unnecessary posts are going to be removed.
It is better that it is deleted rather than you are going to be banned.
