The Points system was badly interpreted by many members and we are not supporting it anymore. The only thing that remained is the ability to mark valuable messages but standings are no longer available.

Basically, also from what you said, those markups represent messages that have helped. So, just click on the icon to mark message for help. That's what it is.

You may get more information from the help on the Points system.
