I'd rather if mk weighed in here, but as far as I know these are because there used to be an ability to vote down on posts which could be used not as intended. If you hover over a share button it has a few fields. (I realised this could be interpreted as "As far as I'm aware a nefarious feature existed that I totally never knew about or used before I mentioned it". It was fun to find out about.) <a id="down_106576" onclick="return vote(this)" href="http://hubski.com/vote?for=106576&dir=down&b... src="images/img_trans.png" class="2-s-point-h">
</a> Where the part you're interested in the bit here:
http://hubski.com/vote?for=106576&dir=down&b... In Psuedocode this is
vote?=for [Post Number]; dir=[Vote Direction, Up or Down]; by=[Username]; auth=[String that verifies you are who you claim to be];whence=[URL in hex] Setting dir=down is for unsharing when you've shared it. When you submitted a content form in the past it wasn't checked if you had shared it first, so you could write out the link as dir=down and it would just keep letting you unshare. For the record, even if you know the auth string it won't let you vote if you're not signed in. I did check, you just get a user mismatch error.
Every so often I have a vision of Hubski as a sleek rebel battleship tearing through deep space at a large fraction of the speed of light, pursued by several vast Slithan attack fleets unleashing electric death, beams of terrifying energy glancing off its hull, sparks flying. Somewhere inside the main deck, after a particularly brutal hit, the lights having flickered into darkness and back up again, someone screams: 'My God, they hit the primary magflux distribution coil, we're a sitting duck.' Outside, moving so fast it's a blur, a sophisticated drone dodges sparks and minor explosions and heads directly for the damage. It comes to a halt long enough for us to catch the marking on its exoskeleton: MK001. Meanwhile inside the ship, the crew members breathe a sigh of relief as over the crackling comms channel MK's voice is heard: 'Fixed.'
