OP, the most likely scenario is that someone has identified you as a spammer and is reporting several of your posts. So worry about writing constructive posts, to the best of your ability, because you will easily get reported if you write garbage posts like some of the deleted ones.
Moderators can sometimes make mistakes, but being several posts deleted, the problem is not the people who report them or the moderators, the problem is that they are garbage.
See i don't make a post because i want to meet up weekly quota. I respond to post because of the content of that post, what here for, is a deliberation and making your own opinion. What i post is like a personal suggestion. Some of the post it deleted it's not because it's a low quality post, just that someone is reporting it.
I don't make a garbage post. Because when you check the post they reported in beginner's and help board, you will notice that some of the suggestion made by other people my post has a quality than some others but still my post is deleted. In this aspects it's someone who is reporting it, and it's clear something. If i should report some of the post i don't like, don't you know that many people post will be deleting everyday.
You made a post and a reputable user of forum quote you and respond positively. Is that post a low quality and which is deleted. This need more attention
