The penalty for an unsolicited fax is a fine (up to $1500) only.
Jail time is not possible. Further, the judgment is levied by your
local Justice of the Peace.


Judgment is not a local event by a Justice of the Peace for a federal
crime. Wrong court of jurisdiction.


Nope.

47 U.S.C. Section 227

"(3) Private Right of Action. A person or entity may, if otherwise
permitted by the laws or rules of court of a State, bring in an appropriate
court of that State -
(A) an action based on a violation of this subsection or the regulations
prescribed under this subsection to enjoin such violation,
(B) an action to recover for actual monetary loss from such a violation,
or to receive $500 in damages for each such violation, whichever is greater,
or
(C) both such actions.

If the court finds that the defendant willfully or knowingly violated this
subsection or the regulations prescribed under this subsection, the court
may, in its discretion, increase the amount of the award to an amount equal
to not more than 3 times the amount available under subparagraph (B) of this
paragraph."

"Under the [Telephone Consumer Protection Act], recipients of unsolicited
fax advertisements can file suit in state court to collect the greater of
$500 or actual damages for each violation, and/or obtain an injunction (a
single junk fax can, and often does, contain multiple violations). If a
court determines that the violations were willful or knowing, the damages
can be tripled at the discretion of the court."
