Nothing prevents someone from following you on your instance. Knowing the sum of your interests gives me more information than the sum.
So, to avoid having your profile being made and exploited, you could split account by interests.
As an example: Someone interested in videogaming and driving Ferraris has a lemmy account he uses to posts on both subjects. Some mar*keting bot wil report “This guy certainly has a high budget for his videogames. Let’s sell him expensive racing games with exclusive Ferrari logos & goodies”. If that person had one account for video games and another one for ferraris, he’d be protected from that.
But yes, everybody should feel free to use a single wide use account.
