Hi Dan, Ned or any other steemit developer,
I was playing around in steemit and I think I found a pretty serious bug in the voting system. I noticed that when I upvote the following 'story'...
...the upvote was being removed automatically again. That's probably OK, since that post is marked 'archived', I guess.
Without the need to wait for the minimum voting delay of 3 seconds, I can vote directly again for that post. And I can repeat this as much as I want (not limited to the voting limit of 5 times). That's still OK... I guess... sort of.
But the real problem is that all these votes are still being recorded in the steemit blockchain!
See for example these ten votes, all for the same 'story' mentioned above, and all together executed within 27 seconds (which is smaller that the 30 seconds it should minimally require):

With this bug present, it should be very easy to write a small script that can executes these kind of votes automatically and in that way spam the steemit blockchain significantly, and at least temporarily take down steemit, which is not cool! So please, take note of this bug and fix it ASAP!
Hopefully this post contributes to a more stable steemit platform, because I love it very much!!! Good luck fixing with this bug!
