Lemmy is a federated FOSS forum-style social network. Anyone is free to create instances, and I knew one day this would happen.
Ideas are implemented using tools. Tools are not bad themselves, the ideas are depending on moral conscience, generally guided by a few set of rules like not letting people fall for vices of life (excess of anything, sex, drugs, gambling et al), or critical information that threatens their lives, or people being stopped from harassing or discriminating against others.
Avoid the instance like you do Gab or Parler or whatever the hell is out there. Internet is a virtual manifestation of the real world with a lot of pseudonymous and deanonymised creators and users. Learn to live with it. Improvise, adapt and overcome.
