I added a new trading rule: Don't be a dick.
If a majority of the people who frequent the trading forums think you're being a dick, then you're being a dick. The punishment for being a dick is to take the crowd-sourced criticism to heart and use it to better your approach to creating threads.
Since it seems like you are deaf on the issue, I will walk you through this. Here's what you will do from now on:
Consolidate all of your sale threads into reasonably sized groups of similar items. Using common sense is key here. Having 3 or 4 threads is fine, provided the threads have some meaningful segregation. e.g.[Many Accounts] Level 100-250
[Many Accounts] Level 250-350
[Many Accounts] [INSANE CHARS] 400 ED, 450 RP, 375 MS, 230+320 EK MAKERS, MORE
[SELLING GOLD] [INSANE ITEMS] Ferumbras' Hat, 3x Golden Boots, Full Master Umbral Set
I like you as a person and I like PvPing with you, but I like my staff more; they are my staff because they are some of my best friends. If I continue to see you (or anyone for that matter) going on ridiculous crusades against my staff citing "conformance" to the fine print of forum rules, I will step in. Don't forget who makes those rules.

EDIT: I just want to also clarify that the reason we do not have such strict rules about trading is the same reason that we don't censor the words "ibot" or "windbot", and the same reason that we make sure all types of conversation, regardless of any taboo subject matter, are accommodated: the staff at XenoBot believes that our users are intelligent enough to decide what is appropriate and draw the proper boundaries. We also believe in censor-free speech. In this case, your decision making failed you when it came to deciding what was appropriate.
