Took a look at the Nexon "careers" page

I was very active during the time they announced that volunteer group and saw no involvement from them other than those lame introductions they would post about themselves on the main site. The game was still in very bad shape then and Nexon is actually better right NOW than they were when MWLB was out. If they interacted with 1% and you were part of that then that's cool I guess, but other than that their presence was barely felt.

Though I am not so sure about them being better now anymore though ever since the anniversary patch. But prior to this everyone could say Nexon has stepped it up and patched some major public stuff that was very damaging to the game amongst other things.
