Does this constitute cheating or is it against the TOS?

Dont sound too bad to me. In fact this is an interesting idea, if not good. Undercutters suck! Theyre the Walmart of MMO's! I always thought there should be some regulation on the AH, like a minimum value for items. Having a free market is great in RL because there is a certain value on time and a necessary minimum living income over time spent on resources and manufacturing. Not so in MMO's where we are all just playing a game and while there is an interest in making profits, there is also interest in just getting rid of it for more than vendor change (undercutters). I do this myself to a degree, buying from the next guy up from the jerk who obviously put the item up for 5g less than the next guy.

Of course it can also be a double edged sword where this "cartel" can monopolize the market and charge whatever they want.

As for the tell, im not sure if its harassment or recruiting. I like how theyre seemingly fighting undercutters in the form of a union but it can also be interpreted as "join us and we'll protect you from ourselves."
