First, I'd like to know if this is an ERP thing. Cause if it is, disregard this entire post and I'll gladly delete it.

This is a lot of tl;dr for me but after skimming, how about you do what I do. Not respond to negative emotes or block them from the chat altogether. As for assassinations, lol wat. Unless they're threatening to kill you irl there isn't any PK.

Also, it's just the market board. If someone undercuts, ignore it. I sold high value items for a super cheap price before knowing their worth but I was the only one who did it. It's not permanent, they're losing profit and I highly doubt the price will shift if no one acknowledges it. Lastly, crafting is crafting. It's not like ERP prostitution where your goods are entirely individualized. If I hit the same level as you, the only difference would be the dye and/or quality provided I bothered with crafting it that way.

Again, this is too long for me to care to read so feel free to correct me if I missed your point.
