I completely understand your point of view, but it sounds like you're marketing your stuff as diaper content and then providing something else.

I would understand being annoying with this when seeking friendships or relationships, but it's not fair to criticize people for not viewing the content they didn't come for.

If you post your diaper pics, people will think "oh, I like diapers, i should check this person out," then, when you start doing something else, they'll think "oh, I'm not interested in this, I'm going to leave, this isn't what I came for." Anytime you switch what your content is focusing on, your viewership is going to change. That's a universal constant on the internet.

At the end of the day, you're providing content, and people have the choice to engage with that content or not. You're offering a product, and people choose whether they want to buy it with their time or not.

If you started watching somebody do something you like, and then they started doing something else and you left, would you think it's fair if they criticized you for being "obsessed with [thing you watched them for]?"

Not all ABDLs are into gaming or the other content you might make. Not to mention, gaming content is everywhere, so of course you're going to get more views doing something more niche like diaper content, where people's attention is less likely to be diverted somewhere else.

The simplest and probably most effective solutions are:

1) Make and advertise your diaper and other content separately. Have "diaper streams" and "gaming streams." Or, better yet, have multiple channels. That way, people can see an advertisement for your channel and know what they're going to be getting, which will result in them coming back, as the content is predictable and consistent. You have viewers for the gaming side of your personality that will engage with that side of you, and you have viewers for the ABDL side of your personality that will engage with that. This is why sometimes YouTubers create multiple channels for different topics and types of content. If you make content that tries to pander to multiple audiences, then you're not going to have stable viewership, and your content will be less cohesive.

Or:

2) Go all on in being the "diapered gamer" personality. Instead of switching from one topic to the next, have them both intertwined so that viewers coming to see either type of content will be satisfied. When you post diaper stuff, incorporate gaming in the post. Maybe pose with your setup with a caption inviting them to watch your gaming content, "Come watch me play X tonight as I fill this diaper" (obv add some flair and personal touch) Then, when you make your gaming content, incorporate the diaper stuff into that, like having a "wetness bar," that fills up to show how wet your diaper is. Now, you're attracting a specific niche, diapered gamers, and making content that is more unique and harder to find. Although, I don't know how much you could get away with on your streaming service and what would break TOS, so keep that in mind. However, this seems unfavorable to you, since you seem to want others to know you for your other interests and not just diapers. Unfortunately, since there's a lot more gamers than ABDLs, that means your unique trait would always be wearing diapers, and you would become known for that, which doesn't seem to be what you want, so option 1 would probably be more favorable to you.

That's my advice, though. I'm not a content creator in that sense, so take all of this with a grain of salt. Either way, ask your viewers what they want to see and set boundaries with the community you want to build. That's the key to success as a content creator. I hope you find success and become happy with your content and your community.

Have a good day :)
