Stop using chat logs. You are literally getting people scammed and it's your fault, whether you believe it to be or not.
There is no security in using chat logs whatsoever and it's a really stupid idea to use them to begin with. Scammers have been using chat logs to trick the 'smart' people with high feedbacks into the newcomers/people who don't market and the people who do market and gain a lot of rep keep sending chat logs and getting people scammed. The most recent one against someone just proves that no good can come of chat logs and it can easily get people scammed.
Instead of sending chat logs, PM your Skype name, RSN and the trade details. Nothing more, nothing less. It is literally impossible (unless the person is just retarded and is helpless at that point) to get someone scammed by this method and this is what I've been doing for a few years after I started getting impostors copy my chat logs.
Honestly, people should be held accountable for their negligence in the market when it comes to trading as you're supposed to be the big shot but you can't even protect your customers from simple scams. Though I'm making this in reference to someones scam report, this goes to everyone - especially since I've made topics on this before. I've had some customers myself who backed out of the trade because they were unhappy with my PM (I pm'd my Skype, rsn and trade details) and insisted on me sending chat logs. Whether they were just people who were trying to act smart or impostors, no one knows.

If you have an argument on why chat logs are actually useful, please let me know as I will shoot it down because it's the worst thing you can PM a user right behind 'I'm talking with you'.
PS: I would post this in suggestions but it already got shot down in the past so I'm posting this as a community reminder.
