After reading everyone's replies I have to say...Lesson Review:
1. Cochy believes that the end justifies the means. If his guild keeps him guilded than they believe the same and this will become a part of their guild rep.
2. Don't rip off legit players even if you think they are easy targets.
Calaglin I see where you support what Cochy did because you feel it's an ingame mechanic working as intended. It's not intended for ripping off players. Trade scamming...definition...agreeing to the terms of a specific trade of an item in trade for money in game. Nowhere in the trade was a duel bet agreed to beforehand. Therefore what cochy did was wrong. He may have seen that player was a noob and possibly that English was not his first language. Just because English is not the first language of player does not mean that they are a plat farmer.
On crushbone we have quite a few Spanish guilds. Just because English is not their first language does constitute them as botters or plat farmers.
This does hurt Disso because with Cochy being suspended quite constantly lately they lose their assassin. Most legit good raid guilds would have let him go over this crap or at most would have docked him dkp and made him sit even longer once he was back in game and possibly demoted him plus still made him pay the plat or possibly paid the plat for him and they docked it from him somehow.
Yes this does make Disso look worse as far as guild reps go. If they don't care then oh well...nothing to be done about that.
After seeing this I suspect some people will refuse to business with Cochy in the future over not wanting to get scammed by him. He will now be known as an unsavory player with no conscience who will scam and rip people off and not feel sorry.
To those who support what he did....well guess you have no moral or ethics either gratz. Hope the people on Nektulos are taking notes on who to put on ignore and not do business with along with the other folks form other servers who support Cochy.
Cochy you know sweetheart you will be banned soon if you keep this up....hope you wise up and fly straight. If not...well...start searching for another game to play.
