It is at the bottom of this pinned thread. Welcome! Please read--
Most MVPs just do what they were already doing which is usually answering questions, linking to information, etc. Esp in TS/CS. Those folks were already doing it, and were asked if they are willing to still do that, but in green. They did not apply. That is about it. It helps people find a post faster that is more likely to have current information, instead of trolling them and telling them to ALT-F4.
For the WoW community MVP program in 2018 they did take applications. Again though, it was for people already active on the forums and most had good intentions - like Neall with friendship moose, Lull with transmogs (although she was already green but everyone had to apply again I think?). A few wanted it for personal promotion and to build their brand. Those did not last long.
2018 was the last time they did the WoW Community MVP program. Last TS/CS person was asked to be involved in 2019. People move on, change games, life happens. A fair number also now work in the gaming industry and stepped down to avoid conflict of interest.
