Just no that no matter what you do or say, you will get called a "Newgen", it has happened to me before, they will stop doing it after a few weeks, probably.
Just know that the stream is meant for shitposts, even though a lot of people don't do that, but it's good to make 90% of your posts there be reposts from all over the internet, not original memes.
Here is a link where a lot of people including myself get shitposts from:

It's okay to do occasional ragebait (Post that is intended to make people mad), but doing it too much will make a lot of people hate you. I have a lot of experience in this.
Don't take insults or anything like that too personally, it happens to literally everybody.
If you want to know anything else, don't be afraid to ask me, and any of your stuff I do see pop up I will upvote to help you get points.
