Whether a non-Article III bankruptcy judge can write and enforce their own law on vexatious litigants that violates the constitution

QUESTION(S) PRESENTED 1. There are no vexatious litigant rules or statutes currently in effect in Federal law, only in state statutes. Therefore, can a non-Article III bankruptcy judge write his own law on vexatious litigant that violates the constitution and enforce it? 2. What should the federal rules on vexatious litigant be? 3. If a plaintiff has been declared or sanctioned as a vexatious litigant and the ruling, he was sanctioned under is either unconstitutional and/or the new rules on vexatious litigant in the second question would not make the plaintiff a vexatious litigant, should the vexatious litigant sanction be vacated as well as any related orders on other cases? 4 If a Court denies a legal in forma pauperis motion and declares the motion as frivolous based on another panel’s ruling involving another courts unconstitutional vexatious litigant order, can the courts pile on sanction fees to a total of over $5000 when the Appellant only had a surplus of $2.00 per month at the time?
