Is the McGregor (from the link you supplied and I followed it to discover the OP of that thread) guy truly a member of the scamming team as alleged? I am going over to draw his attention to this.
It is also a shame that trusted members which are giving negative trust every little shit out there is not even commenting on this issue.
Report this to the moderator or to the Meta session so that the guys get their red painting.
So what, you were hoping that if the bounty pool is $10 000 and you're the only one participating, you'll be getting $10 000 for doing nothing except having a small tag under your name?
Come on, don't be naive. An agreement is an agreement. It should stand that way except it is conditionally stated in the beginning that a reduction may occur later. Without that, changing rules if engagement at the end is a breach and should be seen as a scam.
