Here's why...
....now I doubt he will ever return.
As far as I am aware, I am the only person actually processing scam reports right now. Labeling someone as a scammer requires gathering and summarizing a great deal of information in order to build a case. It's not fun... and all it does is put a label on them. It can easily take a hour or more of work over several days per scammer to get them tagged. As such, I prioritize the work in a few main ways:
1) Scammer rings. I process these IMMEDIATELY. You've seen the damage they do.
2) Misunderstandings. These are the most likely to result in an acceptable resolution for both sides. I might actually
accomplish something.
3) Active scam account. These guys still use their account, and I can't tell if they're PMing people to get one last scam in. They need to be labeled to warn those people.
If someone isn't active anymore, I could care less about them. If you care enough, gather the evidence and process it yourself.
