When I first joined this forum, I did not see reporting unwanted, other spam posts and posts on the wrong board as interesting, but few months after, it was interesting for me. Not that I made it a job, but I noticed that I just feel good to report the posts as I also like some red tags on my trust history which I think is good for this forum, to help against spam, and scam most especially.
After 600 (not sure the number) reported posts you get that button "report history". I was happy when I got mine! I still have only 896 reported posts. Keep good work!
