Since you are clearly struggling to justify your rating, here is another example.
Let's pretend the terms were stated in the OP; that I will pay $15 for someone to find the EXACT sunglasses. Let's say the thread is 6 pages long and somewhere in those 6 pages I state that I no longer plan on paying a reward. Obviously everyone will see the OP but it is unlikely that they will see that the terms have changed, which would be deemed unfair.
Even though the unchanged OP clearly states the terms, I no longer have to pay a bounty because I buried a response in that thread that overrules the original terms?
Is this what you're trying to say? Because if this is so, the mods need to review your account. All I have done in that example is switch the current scenario, thus highlighting your misjudgement.
Wow! I never thought you'll be back to defend your self. I was one of those who actively searched for that glasses but unfortunately I didn't find the exact match, but what made me continue to search for the glasses, it's because you said who ever give at least the nearest match will get something and I said to my self not bad at all so I continue. If you didn't posted that, I would have stopped and moved on. Anyway that's done and good luck to you.
