You are right: You are not posting that often, but when you do, you broadcast it across many different communities - which is also a kind of spam.
Normally, other people will x-post interesting stuff, if they feel like it. You could stop spamming by posting to only one target.
Also, please read the room: I feel like due to the countless issues raised (a long time) before, you should first address those before posting again - as we nerds like to engage with at least something valuable, but this project is currently a burning dumpster fire.
