If you're posting things in the wrong section or making spammy posts, moderators might be moving or deleting your posts. Just be careful what you post and watch where you put it, and you should be fine.
Please note that when you post a new topic in Tips and Tricks and Tamagotchi Codes, they require Moderator approval before they appear in the forums. I noticed that you had made multiple posts of the same topic - any of these will be deleted and only one of the topics will be approved. Sometimes it may take a little while before topics in these forums are approved or deleted.
