Appeal to spite
From Iron Chariots Wiki
An appeal to spite is a fallacy in which spite is substituted for evidence when an “argument” is made against a claim. When successful, it manipulates the listener to question where and/or with whom their trust lies.

- Creationsts point to the well-known hoaxes Piltdown Man and Nebraska Man implying or claiming outright that this is representative of scientists who used fossils to demonstrate human evolution.
