Your posts haven't been removed they have been down voted, or flagged, because the content has been found to be copied from somewhere else on the internet. If you did in fact write them yourself then you should go to @submarine and give them proof that the content is yours. They will then remove their flags.

It is not acceptable in many cultures to try and make money from someone else's work, so if you make sure to only post your own writing then you will have no more problems.

I hope this helps.
