I tried to make a multiverse setting using Greek Letters, and the setting of my current story was going to be the Omega-Verse. But once I realized what it referred to, I had to distance myself from it because my story was meant for kids and teens, and the search term was going to land them in hot water with their parents if it didn't scare them off or gross them out entirely. It's definitely adults-only.
Even at that, I didn't want people to misunderstand what my work was about, and create fandom content that scared away other fans.
I think if you're going to make Omegaverse content, you should do so knowing that your biggest fans are the ones who already like it, and that if any major platform sees you making it, they aren't going to feature or support you. You need to mark your work as explicit.
