Of the three theories I've read, all of these theories are true and often occur in several projects. However, most projects are popular because they promise rewards for certain roles, but some projects don't keep their promises, thus causing the project to die.
makes discord quiet because there are no activities or events, many projects like that.
This is the answer to 3 questions based on my experience:
1. I attend many projects because of the rewards they promise for certain roles. I usually attend from the beginning to the end of the project, such as Caldera, Xion, etc.
2. I don't do or use language tricks, I chat as usual naturally, asking questions between members, usually discussing the project, and I'm most active on the Indonesian channel.
3. like the announcement of the role level in discord, which forces me to be active and chase the discord level, because they promise rewards but sometimes they change the rules.
