Only a portion is crossposts from .ml comms to non-.ml comms to grow off.ml alternatives and reduce .ml's influence because of the toxic behavior of its admins so that other instance admins in the future can make a defederation decision without having to worry about cutting off from "big .ml comms"
I aim for a minimum ratio of 1:2 crosspost to "organic" posts so a majority of my posts are in fact my own lmao
