TP can get super frustrating, for sure.
I was on the other side of that just a few weeks ago, where I was trying to sell two MPs I got from rare events. Due to personal preference, I don't like dealing with Baby PBs, so I specified PURE in the lot description and said Neomail to offer.
The number of people who ignored that and offered Baby PBs plus a bit of NP without bothering to shoot me a NM, and then got offended when I rejected their offers...
One person made the offer SEVERAL times, and after the third or so time sent me a very angry message telling me I was a horrible person for not accepting their generous offer.
Another person messaged me a bunch of times after I rejected them, trying to argue their case. My good sir, arguing with me is sure as heck not going to make me change my mind and sell to you.
In the end, one of the MPs I sold at a 1m discount to a polite person who didn't have as much as I was asking for in their bank but could actually follow instructions and was undemanding about it. The other one I released it in a giveaway here.
I'd rather they go to people who are nice than make more money selling to rude people who can't read.
