Looks like people are forgetting that there is an appeal system. If you feel that your posts have an unfair lack of merit points, all you have to do it make a post here and someone will probably merit them if they are meritorious.
I still think this is pretty desperate behaviour. If this becomes standard practice then Meta is just going to become chock full of people just creating threads asking for merit which isn't really much different than just asking for it in the thread or post itself. Imagine if people did this for feedback:
Hey, I did these handful of trades and nobody left me positive trust... Can someone leave me trust? Merit should be a natural process. If you create a thread or post and it goes unnoticed then oh well. Better luck next time, but complaining every time this happens just seems wrong.
