The format is followed, the flag system is just broken. Once OP updates the initial first posts, then the flag will link to this thread which links to multiple violations (one of which will be the escrow scam). You can't link to a locked thread which is absolute nonsense.

You must create a topic describing the specific acts which damaged you. It must not be self-moderated.
This is fundamental flaw in the flag design and can be skipped. I'm not letting scammers like Quickseller go because I just didn't happen to be a victim too. 
If mr. Theymos really insists, I can make a duplicate thread of an existing thread from 2015 just to link that in the flag. What does this accomplish exactly? Nothing.I will also second my brother nutildah, the format has not followed.
