Is constantly posting in my Instagram and Threads saying “i will become more successful than my former friends and I will make them jealous” toxic?

I keep replying to threads that talk about fake toxic people and friends and I reply saying my former friends name and talking shit about them even though I have them blocked, like for example “they aren’t anywhere near as smart or successful as they think they are” or “they know nothing about me or my achievements and that I’ve done adventurous things they can only dream of and they are secretly jealous” and “they are all low IQ fake, lack empathy, and their whole lives revolve around validation” I didn’t tag them because they are blocked but I have a friend who follows me on Instagram that is mutual friends to them and even though she doesn’t have friends she may view it. But what will people specifically my former friends think of me if they say my replies?
