Thank you for your support! I would like to create a discrod server but I'm wondering if it's possible for me to keep doing that as uploading my images will most likely get me banned😀
I think it is worth trying. You can mark the server as adult-only and there is an easy way to make users 'react' with a particular emoji to make sure they understand the rules before gaining access to the rest of the Discord server, many adult-only servers do this.✌ If you are posting the same images you post here things should be fine.
uploading nsfw images is completely fine on discord as long as the community will be only for those who are 18+ by having moderators to kick who identified themselves under 18 and by simply age restrict channels , and getting banned on discord isn't possible for uploading nsfw content in channels aren't age restricted, you will just get disabled for posting such content publicly for all ages, I think that's what happened to you since you didn't know the function of making a discord server, and discord itself supports such work of yours as you may get your server verified since you own a popular game and you picked discord to make a community for your game
and again, if you want to create a server for your community and to make it easier for them to feedback. I am at your serves
