Extreme Undercutting - Should it be a violation?

[Paladinleeds]

EDIT2: I accept listing the report has caused misunderstandings and probably shouldn't have been included. That being said, I appreciate the constructive discussion this has lead to. I'm glad that a moment of rage for me has been turned into something productive and opened up a mature debate. Thank you for that. I am reading replies, don't worry! Even if I don't respond to you, I've read it!

EDIT: FOR CLARIFICATION. Yes, I reported MYSELF to the GMs for this. Not another player. Myself. Because I was told I was griefing other players by doing this extreme undercutting. I acted upon what I had heard from other players. And I felt the GM response warranted a thread opened to discuss this. Please don't think I'm trying to say that one person should control the markets

So, after a heated and angry me decided to report myself for extreme undercutting (90% undercuts for example, to try and lower prices) I was responded to with this.

Greetings (name),

Thank you for your call.

We're deeply sorry that your game experience is disrupted by another player. Unfortunately, undercutting in the Market board is not a violation to our rules and policies, therefore we're afraid we won't be able to assist you in this case.

We would be very grateful if you could submit any suggestions or comments on our official forums. Your feedback will then be forwarded to the appropriate department by our Community Representatives. We remind you however that name shaming is strictly against our forums guidelines, therefore we advise you to share your comments without referring to any specific player.

Although individual responses aren't sent, rest assured that all comments submitted are read and considered for future updates.

Thank you for your understanding and we apologise for any inconvenience caused.

So, currently it clearly isn't a violation. But do you think it should be a violation? Why do you think so?

Personally, if it is deterimental to the experiences of other players as I have been told it is, I believe it should be. I do believe experiences which severely negative impact the experiences of others (as I believe severe undercutting is), should be punished. But what are your thoughts? Let's turn my heated and angry moment into a useful discussion.
