ok i have been around trading for a few years and guildbank trading might be one of the safest but it isn't bulletproof 100%. a year ago Blizz delete half of my guilds( over 20 total) with gold in them and ban the guild leaders account( fortunately not my main) ..... ofcourse i opened a ticket as a member of one guild...but the response i received is that the guild i was in was violating the economy(something like that)
i just wanted to share something to the conversation .... :P
