Why it is being deleted or removed?

There is no guidelines telling us not to post adult content. Also when we receive a notification for deletion, the reason concerns the topic unless it was only our specific response or comment that was removed.

I think most probably it might be related to some rule violation and that is the reason that the discussion get deleted. I think it depends on the content of the discussion.

Not only your discussions was deleted. I was also deleted when the title "I reach my 1000 posts in Mylot". Well, its ok me. I hope your doing good there.

I don't know! My best guess is maybe it had something to do with the topic. If the discussion was about religious sin and the comment was adult content maybe appearing to be offensive in relation to the topic then that could be the reason. Sure there are better and worse but I think content has a lot to do with it. That is a guess. To explain further what I mean, ficticious example, Nancy's mother starts a discussion on her daughters barbie dolls that would be appealing to say a family/youth audience, someone makes an adult comment and it is deleted because it doesn't match the topic. Don't know if that is what happened to you though.

Yes, you are right friend, if we cannot talk about "S" why in this site provide interests on "S"? I also confuse, But I never think about it, I just post discussion that does not related with the topic. Yes, I think there is no perfect site.
