The images of the time log is not a good evidence for convicting someone of a Scam Accusation but I do believe that the @Darkakula is an alt, I have looked into the post history and I saw that the user in the Digital Goods child board, specifically at the Invites & Accounts, that is a pretty deep part of the Marketplace Board and I do not think that if you are a newbie, you would be thinking of going there for your first day as a user in this forum. I am not saying that this person is an alt account of the accused but I do believe that the one that I @ is definitely an alt account of someone.
If you have at-least some confidence that it could be alt of Vareole then leave a neutral tag on its profile referencing your post above or this post. Whoever wants to deal with this account hopefully will see the feedback and read the reference. It will help to do the due diligence by their own.
I am not leaving any feedback yet until I find a solid proof. Perhaps your feedback will help in the future to understand about this account in question a bit better and for any wrong doing it will lead DT users to tag.
To be honest, I do have confidence but I do not think that leaving a tag without hearing the other side is not the most rational thing for me to do, we also shouldn't rule out the possibility that it might have been a big coincidence that the universe itself created and that @Darkakula might have been a long time lurker. What I mean by that is that we all should give people the chance to explain their side of things before deciding ourselves, remember that we are not a judicial entity so I do not want to just go in and put up someone as a scammer, I am sure that you can understand, even a neutral will be defeat my principle and we all know how a tag can be problematic for someone in this forum and I also do not want this forum to become a kangaroo court where everyone will just be guilty by just presenting some evidence that is not enough.
