The 500 shares was in reservation by berrylonly he didn't pay so now are availables again. Easy. There is no need to blame.
Nobody is blaming. Do you understand what "logic" means? Check this out:
http://it.wikipedia.org/wiki/Logica (WARNING, it's in Italian).
It goes something like this: you collect facts, you make reasonable assumptions and then you use your judgement to make logical conclusions.
E 'più o meno così: si raccolgono i fatti, si fanno assunzioni ragionevoli e quindi si utilizza il vostro giudizio per trarre conclusioni logiche.
In this case, we have facts: number of shares that you stated were purchased. Then we have more facts about you stating "last 100 shares", then "last 500 shares" being available. Facts contradict each other ( I fatti contraddicono a vicuna).
We make an assumption, a very reasonable assumption, that you either can't count or trying "mind with mind" again. Then you come up with a new "fact" that there was a user who owned 500 shares and now these shares are available. Well, it may or may not be true. If berrylonly speaks up and says "yeap, my shares are available for grabs", then it would actually become a fact (effettivamente diventare un fatto). That's cool. Absent that confirmation, we make an assumption (again very reasonable) that you made up this person.
It all boils down to the last critical point. This point is making a decision using our judgement. I have some money now. DZ MC GB fucked up (indirectly) and I have funds available. Will I invest in this GB?
No.
P.S. I am from Russia. Logic is the same here as in Africa or Australia.
P.S. Sono della Russia. La logica è lo stesso qui come in Africa o in Australia. Capisci?
