I'm probably stepping into something I don't really want to, but I feel like I need to voice my opinion on this too, even if it's stuff said before or being written as I type to post. Oh, and do feel free to add, agree, disagree with points made, as I don't have all info, only going by what I have understood of the thread so far. So do point me out if I'm missing something.
Firstly, I wouldn't label someone (the wiz) as being greedy and action taken on them (blacklist, ignore, whatever) yet for a few points:
1. We don't actually know what the Wiz meant by saying "I don't need it".
I wasn't there, a good deal of us wasn't there either. I can only say that "I don't need it" can mean a lot more other things than "I've got base stats of 50 everywhere, and I've used said tome before too, I don't need it". I don't remember the original poster putting up exactly what this Wiz said, only what they remember of the conversation taken place. And this is only one sided. You should treat it as such and only put caution on when encountering this Wiz, not act on it as if it's unbiased, not mistaken, not misunderstood or something along those lines at this point. Any other response would seem unfair and rather harsh.
Personally, I would apply a Innocent unless I can prove they are guilty. If I see another +3 Cha tome that is unshared, and they aren't saving up for some rediculously extortinately priced item on the AH, then I would say (at most) greedy then. But not before.
2. Need. Who really needed it?
Again, I don't have transcript or full details, but the original poster said that others "could" have used it. Unless these others come up to post and say that yes, they had a "need" for one and "could" have used it. ie They haven't used a +3 Con already, or it would actually make a difference to their rolls. I wouldn't really class it as "need".
In the beta, I was rather notorious for pulling tomes on a continuous basis. I only started to pull the +2's near the end, but would it actually be greed if I pulled one and used it on my Monk character first? I certainly don't "need" it, but would certainly be useful. Again, back to defining the word of "need" at the moment (like point 1).
Hence, why I would suggest caution and restraint on instantly "blacklisting" this Wiz. Whatever "blacklisting" means to you. For me, it means total nothing to do with them.
3. Back about the AH. Did anyone else actually offer anything when the offer was made?
According to the original poster, no one even offered anything. If one person said to the Wiz, I'd like to offer you all I have (5k plat only; total fortune), there was engagement. Rejected. But still engagement. Right now, from what the original poster has said, none of this even happened (please do add info if this was not the case). Which means no one even said they wanted as far as I'm concerned (My view only); as no one expressed interest.
Since we don't know if the Wiz was looking for plat to buy stuff that's clearly over inflated in the AH. It can't be expressed as greed, as they might "need" something in the AH. They are simply not "trading" with anyone in the group, as no one expressed interest. But they have "need" of it, as it's being changed to AH capital.
Now, unless you know for a fact that this person has got EVERYTHING already, then it should not be classed as greed.
For example, I pulled every +1 tome available inside 2 days in the beta. With multiples of each. I also had money for the AH and didn't need to use them again as they won't work. If I pulled and wanted to trade and got no offers, and then decided to take it, THEN would I be greedy. But of course, you know all this as I just told you. We don't know about this Wiz at this time. Again, should not be instantly "acted" (blacklisted) on straight away. (For the record, I gave most tomes away unless I needed an item in the AH which I could clearly not get, as I did not have access to that adventure pack).
Make no mistake, I am not saying anyone is wrong, or is right. Only that I have noted that many seems to have jumped into the action stage before finding this Wiz and seeing what their half of the story is. Personally, I would only have heightened caution, and not all out action (blacklist) of this character (Wiz). As it is totally out of proportion for only one side of the story.
Err, that's about it really. But, I feel that those should be addressed first before something as major as blacklisting is done.
