Not involved in it since I've seen the horrors talked about before, and it's wayyy too common. Also I think most of the playerbase is way out of my age range of people I'd want to constantly interact with.
Can't say any fanbase is bad until you were in it at least once.
So that's why I can say that the Gacha community is what it is. Of course, there are talented people who make really impressive stuff like animations, stories, etc. But most of it are... mediocre and/or lame. Contrary to popular belief, most of the fanbase are around the range of 14-10. But age doesn't form a fanbase, it's the maturity of the people.
Pretty bad honestly, but not as bad as most Vtuber fanbases or the (once popular) sonic fanbase. If there is a tierlist for how good the fanbase is, it'll probably be in a C or E tier.
