There are some infamous laws about social media. You have Godwin’s law:

As an online discussion grows longer, the probability of a comparison involving Nazism or Hitlerapproaches 1“^[2][3]—that is, if an online discussion (regardless of topic or scope) goes on long enough, sooner or later someone will compare someone or something to Hitler or Nazism.

There is also a second Godwin’s law:

His secondary law is that; as the likely-hood of Nazi’s and/or Hitler being mentioned in a thread, in direct reference to his Primary law, increases, so to must the chances of his own law being referred to.
