Does your ugc page have to be strictly Ugc?

I know this is controversial and everyone has their opinions. But what do you think? I’ve seen a lot of people posting very personal content on their account and I want to do this. It attracts brands still doesn’t it? I’m talking like what if I want to start a series that’s unique to my life and I post both ugc and very personal/niche to my life content? I guess where’s the line on if I should make a separate account ? This just sounds like a pain lol
