A ban for plagiarizing a story carries a 6 month ban. It might be easier to just credit everything to the original name or to change the credit on the other sites to this handle (if that's the one you choose). You can also change your username using this link to avoid it all together. Being uniform is key if you're posting multiple stories on different websites.

That being said, you should probably make it your priority to have some form of proof that you are the original author in the future.
