I made a lot of new posts, all original, and all gone

 I had made a lot of posts that were not copied and there all removed, why? because it was coped when it was not 'sigh' look...I'm a reasonable guy but this is crap...my next post on Minecraft feedback is called '[Nether DLC] The Black Corruption' and it's not copied so if this one gets removed for no real reason at all, I'm going to be made.
