I've had many posts deleted. Once I reposted a deleted post and the moderator changed the text. Now with this username there have been no outright deletions, but a moderator combines any two posts into one then sends the message
Moderators will not edit/change texts written by you, they are only going to merge your posts if you make consecutive posts, which is not allowed in the forum, stop making consecutive posts and moderators wouldn't have to merge your posts again. Then if they trash or delete your posts, then it is because it was off-topic and instead of complaining about moderators, it is better to look at your posts and improve them.
