ULPT-Request: messing with self-proclaimed “local MAGA Rep” neighbor

Neighbor on my street who refers to themself as “your local MAGA representative” keeps leaving political fliers in mailboxes. The fliers are ridiculous… they not only instruct people which candidates are MAGA-approved - they also contain blatant falsehoods about opposing candidates. Potentially libel - but I’m not a lawyer and unsure on that point.

Fliers provide the MAGA rep neighbor’s name and telephone number.

As someone who abhors all things MAGA, I want to make things uncomfortable for this walnut of a human. Only want to consider things that are strictly legal, so afraid that piss discs are, regrettably, out.

Would love ideas, fellow Redditors!

Edit: my inbox has 50+ comments all saying the same thing - that placing non-mail in mailboxes is illegal. So, editing to add that I’m aware of this, have reported, and am pretty confident they won’t prosecute or fine this person. And so considering alternative (LEGAL) ULPT avenues against the MAGAt.
