Write to the desk
Tell the desk when a number on a firm sheet looks wrong. Do the same if a code stopped working, or if a firm changed the rules before we did.
Address details
contact@propfirms.red is where mail goes. A small team checks the firm sheets and reads every message, and a reply usually comes within three working days.
Add the firm page that shows the figure when you report it, so the check is quick. No paid placements are accepted, so an offer to buy a ranking gets no reply.
