There is nothing like an interruption of the work day by an unwanted, unsolicited junk fax, spam text message or autodialed/robotic telemarketing or debt collector phone call. These things ruin your train of thought, interrupt workers, waste paper, time and resources such as ink/toner.
The TCPA (Telephone Consumer Protection Act of 1991) provides a remedy to attempt to stop these interruptions. Senders of unsolicited fax ads for products and services may be liable to the receiver of the ad for $500-$1500 per fax.
