This is usually because you have the TF2 console variable cl_disablehtmlmotd set to 1. In order to earn points on our servers, this variable needs to be set to 0.

Here is how to change the variable value:

  1. Open the console in TF2, here is a video tutorial that explains how to do that
  2. Type in cl_disablehtmlmotd 0
  3. You are done

Now you should receive points on our TF2 idle servers.
