1. Check the database of a forum once in preferred time plugin user.

    if = the post has been made the tabel with the post will be +1
    On server local store a file if file and database diffrence from each other give a user an item or coin.
    make sure that it needs to diffrence in positive numbers not negatif due to deleting a post or remove privileges on forums to remove posts.

    Not sure if this could be accomplished due to mysql
     
  2. Which forum system?
    You can read out the .json files รก PHP, but ... the local storage on your server has to be overwritten by a plugin.
    I can make you a script, that gives registered members with verified steamid64 an item of your choice or and random item. Quid pro quo? :D
     
  3. Mybb is our forum system. But yeah if its being a plugin then the underlying thoughts are for more than just 1 forum software
     
  4. That's the problem. IPBoard, Woltlab, etc. using all different database columns. So, somebody has to write it for all as a library or you pay a dev for the work.
