Newfags are important to keep a /vg/ community alive since there is always people leaving or taking breaks and if there is no new blood to fill the void there will eventually not be a lot of people left, and then the remaining people are going to start dropping off because of the lack of people. It's a tale as old as time and probably something a lot of you have experienced in other communities in the past.
That's why I'm against curated group instances. /vrg/ does not want to keep new people out, we only want to keep the wrong new people out that have nothing to do with 4chan. I don't think this is it.

I also cannot think of a single "prominent leaderfag" person that does not have biases that would lead to certain people in here being shunned just because of prior drama or other petty he said she said rumormongering.
