While the "attack" Grace noted is a problem, I just experienced this and lost my bounty reputation altogether.
I added a bounty to the question: better jquery scroll to plugin than scrollTo?better jquery scroll to plugin than scrollTo?
And then through my own research discovered there were no alternatives, so I made my own. Awarded the bounty to myself, and :O I don't get the bounty or my reputation back! This just makes me feel like poop, all that hard work, and it cost me 50 reputation!!!
A warning or strike system would be appreciated. Like a we'll let you off this time, but next time you'll lose your rep.
