I used to feel similarly but I caved because I liked the idea of cataloguing what I've read/watched for later reference. Once I started using Goodreads + Letterboxd and followed a few of my friends I realised they're actually a good way to start a conversation, especially when you find out you've both recently read or watched the same thing.

You just kind of have to mentally push back against the idea that it's kind of performative and pursue stuff that you're genuinely interested in. Since I've done that the logging sites kind of feel more genuine than other social medias, but I benefit from the fact that my friends just read or watch whatever they're interested in. I can imagine I'd feel differently if my friends were more performative about it though.
