Plagiarism on Steem is a huge issue and while it was unfortunate you were caught up in the middle of the accusations, I can sympathise with those who assumed guilty until proven innocent because I see plagiarism happen here so constantly, it's become an epidemic.

This is why it is important to put a little note at the end of your posts with something along the lines of (feel free to use this if you like):

I originally authored this article over here and I am republishing it as the sole content owner, here on Steem.

There isn't anything wrong with posting content in multiple places, but the bot owners have had to take a more aggressive stance because it's difficult and time intensive to chase up every potential offender, to the point where more than 7 days could have passed. It's easier for bot owners to ask for potential infringers to make their case.

In your situation, I agree that some of the fast-flaggers and vote removers acted way too hastily. You should be given a chance to prove your innocence before any kind of action is taken. I hope this all gets cleared up for you eventually.
