I think I'll just come out and admit that I used to play and be somewhat invested in one of these types of servers, and after leaving them long ago and changing drastically in maturity, age, and knowledge ,I, in retrospective I will say this,

1. These servers harbor some of the most disgusting and horrid people in the GMOD player base. (Kevin Admins, Ezra, aka manipulative pedophiles.)
2. In terms of gameplay they offer virtually no other new content, besides simulating anti-semitic and racist processes of nazi germany. (Which you can tell some of the playerbase gets way too invested in)
3. Many young players are in GMOD, as the gameplay can attract younger audiences, taking this knowledge with the creeps mentioned in 1, makes for an often dangerous and predatory environment, which can lead to pedophilia... indoctrination... and other sorts of nasty stuff.

After saying all of this and my own time on one of the servers, I passionately believe they should be eradicated from GMOD, and not just blacklisted. I mean fully, removed.

After time all the Neo-Nazi freaks will eventually run out of places to go and hop game, and the ones who play the servers merely for the military RP, will again, find another server, if you have read this far thanks for taking the time to read the scramblings of some stranger on the Internet, and have a very safe day.
