Discord is just a tool, which itself doesn't do anything "good" or "evil". As with any other tool, the person(s) using it decide what it does.
I can understand that some communities on Discord are not the most welcoming places, due to their size or tone used there and I did experiece this myself at other servers, but for the server of DroidProductions I feel safe to say this is a nice and helpful bunch of people, with a very active dev.
Don't miss out on the constant flow of new BETA-builds
Besides this, if you want you can help hunting for bugs or spellerrors or share your valueable feedback.
