It is possible, but I don't think I'll do that, because I also use this app on my main account for stuff that I find funny, cool, beautiful and more. And if it gets comment I'll answer them and keep the community aspect of everything. At the end of the day, this comes down to what the use wants to do with the app.
However, I could add a disclaimer that if the user only post with this app and nothing else, its account should be marked as bot, but I do not want to make that mandatory.
We'll see in the future if the app gets used and how it might affect content here!
