The court noticed:

While reviewing Docket Entry #176.00 (marked "take papers" for August 3, 2026), the Court printed recent pleadings to try to decipher the motion and see what recent pleadings may be related to it. When reviewing the pleadings, Docket Entries ##177.00 & 178.00, seemed to have extra "white space" apart from other pleadings of the plaintiff. Upon close review, the Court has identified in these pleadings, potential text that was formatted so as to be nearly invisible to a human reader while remaining fully legible to software that potentially processes the documents' text.

Rob Freund on X: "Pro se plaintiff attempts prompt injection in motion for default in Connecticut superior court. Court revokes plaintiff's ability to e-file, requiring in-person filings going forward."
