So a friend forced me to be a middleman... (Also a report on a scammer.)

Like the thread says, I was basically yanked into a sudden middleman deal. I don't plan to make threads here very often, I just wanted to get this off my back as soon as possible.

I never did any middleman trades before until now. This guy tried to take off with my friend's Crimson Web Bayonet by impersonating him with a bot with a trade (after taking pictures of me getting involved, which is why I'm here). Geez, and I'm already worried because he might try to make a false report to fool somebody into thinking I'm the scammer, I'm scared to death as I type this.

Unfortunately, I wasn't able to supply enough screenshots to express the ordeal 100% (Again, first time middleman, I got too confident and thought I'd be dealing with a honest man the first time around), but I felt like I had to make this thread before he tried to frame me and/or my friend (Fountain) via general with false accusations.

5.(In comparison with my real friend. Who has no "." at the end and the profile isn't marked as "private".)

Also, just realized I posted in the wrong section, hopefully a moderator will fix this. My bad.
