Sorry this happened to you.
Couple things i pay attention to when entering into transactions on forums.
How long they have been a member on the forum.
and
What is their post count.
I feel like people who have been around a while are likely not gonna be a scammer, this seems to be especially true if they have made a contribution to the forum.
It's not a perfect way of vetting, but it's a pretty easy to go.
Have you inquired of your bank? Sometimes they will reimburse you for fraud.
