I hope whatever measures are adopted, some grace is given to new members who are learning.
I remember early on I dibbed a sale post for some likely below-market chips. I was new, didn't know what I was doing, saw something that looked interesting to me that was affordable. Someone else later came in and were interested in the chips for sentimental reasons, so I gave up my dibs. In PM, I asked if the person who ended up with the chips if was anything like a "finder's fee" for releasing dibs on something, and he very kindly explained it's not how it works here but people help each other by tagging each other when listings come up that might interest someone else, so I adopted that practice too.
If I had asked publicly about a "finder's fee" concept, or if the user who I released dibs to were less kind and understanding, maybe I would have been criticized to oblivion and scared off the board.
(Also within the first month or so of membership I remember asking about selling something for more than I bought for, and I got a pretty harsh PM about how I'd be ruining the hobby. Fortunately, I got other PMs, from sellers I was buying from who cut me a break on some prices since I was new, actively encouraging me that if I were to sell, I should do it at market value, so I can reinvest any profits towards the sets I really want to keep. So there's a wide gamut here.)
