HauhauCS (of "Uncensored Aggressive" fame) published an abliteration package that plagiarizes Heretic without attribution, and violates its license

HauhauCS (u/hauhau901) publishes uncensored LLM models on HuggingFace with 5M+ combined monthly downloads across 22 models (verified via the HuggingFace API, April 2026). Every model card claims "0/465 refusals, zero capability loss." When asked about methodology on HuggingFace, the response was: "Currently it's my own private methods and tools :) Not interested in any donations."

We recovered the deleted source code from PyPI's CDN. It's a fork of Heretic (AGPL-3.0).

Heretic's author confirms derivation

Philipp Emanuel Weidmann, the creator of Heretic, reviewed the recovered source code and stated: "I can say with certainty that this package was plagiarized from Heretic, and then probably refactored using an LLM in an attempt to hide this." He identified the same SPDX headers, the geometric median approach he has "never seen in literature," the DatasetSpecification fields including residual_plot_label and residual_plot_color, the cascading dtype fallback, the good/bad naming convention, and more. He calls it "a clear violation of Sections 4 and 5 of the AGPL. It's also a clear violation of every ethical standard imaginable, and an obvious case of outright plagiarism."

License violation

Heretic is AGPL-3.0, which requires modified versions to preserve original copyright notices, identify as derivative works, and remain under AGPL-3.0. Reaper removed all copyright notices, does not identify itself as a derivative work of Heretic, and relicensed to PolyForm Noncommercial.
