The first deleted post is typically done with no punishment. The next one gets a temporary ban and increases with each comment. That is the general rule. Some people get a longer ban because they commented more that other people.
The rule regarding off-topic posts is called Jaiden & Erin's rule (Please read‼️). It states “ To ensure that this stream does not become another msmg, we ask that you don't post too many offtopic shitposts. This stream is supposed to be as gay as possible. We don't want that to become unclear. If you have queer-related shitposts, you're welcome to post here. Anything off-topic, excluding announcements, drawings, trends, and picrews, will be disapproved. Thanks. Love yall! <3”
The most important part to pay attention to is “Anything off-topic, excluding announcements, drawings, trends, and picrews, will be disapproved.”
