I just stumbled upon a funny Steemit error message...
Steps to reproduce:
- Go to Steemit.com
- Open any post in a new tab.
- Upvote the post within the post page.
- Go back to the original tab and upvote the same post there as well.
It's basically preventing me from "double-spending" my vote and I love the way it is phrased.
Thanks for the post!!
