I do disagree, he shouldn't be going around blowing up your forums, however, I can't say I blame him.
He's currently under the belief that you have not delivered the 300k. You are trying to supersede that dispute by continuing to conduct business.
These are my questions (initial) that I have from the original post towards you.
1. I understand building a false "repertoire" within the game to come off as real-life buddies, but then you went off to help a druid friend in-game? There was no response from you after that until after he had messaged you both in-game, and here on ECTunnel. It was roughly 7:30 (going off of memory) and you said you were in husband mode with the wife and kids? No joke, I called my girlfriend, from the side of a mountain when I was rock-climbing about 250 feet up, because a pending business deal (took several days) had literally just randomly sent the money. She got on my PC, found the exact account info, and texted it to me which I forwarded him. I understand this is an extreme length most people won't go to... but surely your wife would understand taking a few minutes to deliver a product that someone has literally already paid you (and by proxy her) for. (Hell when I make a $300 sale on Everquest my girlfriend rushes my ass to the PC xD) So, why didn't you deliver the plat then and there?
2. You claimed in your initial post that you have dealt with "a few of these new guys" before, which is the reason you strictly use CashApp. I did find this to be slightly off, because out of the hundred-plus business deals I've been a part of. I've only seen this once. Second question, where did these other new guys come from; as I don't remember any disputes about that here on ECT? Just trying to add some weight to your story man.
3. Discretion is the key here, however, the hundreds of screenshots I have from all of my business transactions, including names, dates, times, emails etc... are all safe and sound on a hard drive next to me. Again, an extreme length, but I prefer covering my own ass at all times. Out of the various guides here that all state to essentially get receipts, you have none for what seems to be a pretty decent-sized amount of business?
4. True chat logs can be altered, and only verified by a GM, by chance do you have a log saved somewhere? If so I'd try and find it.
Just trying to get some of the basic questions out of the way.
EDIT: Essentially, I'm trying to get some answers so I can ask Cained disputing or contracting questions as well; just as of now, he's got everything in-hand because he did read these guides and took a lot of screenshots, and you don't a part from banking on your reputation.
