I did not even consider challenging their decisions: it would have implied that I am attaching some importance to occurrences I could not care less about.
I have proudly earned my share of haters over the years: some of them reported my profiles, Meta's obscurantist censors established that my content violated the "community standards"
so all my profiles are now history.. and will remain history.
Their usefulness as promotional tools was close to zero, and with the exception of very few people that I will miss, my social interaction there was also close to zero.
I still have a https://www.deviantart.com/feetosopher that I check every 6-7 weeks, and where I add content maybe once a year
Luckily, I have more entertaining things to do than being active on social media
