Okay thanks. Personally I am a fan of discord as well but I have found that many people are hesitant to click discord links when it comes to joining new groups
If it seems a spam link that you'll just post out trying to join people, it is not going to work because that's going to be looking suspicious. That's why if you want to grow your community, you need to be genuine with what you're trying to do with your community.
It's not just all about the platform or whatnot but it's about the community that you're building because if you become establish, you can simply just go anywhere and your community is going to come with you.
