Bull sh*t.
Your comment ... brought to mind to take a play out of the old leftist passive resistance playbook of mailing garbage and dog poop to their enemies.
Imagine inundating this business with 10,000s of pieces of mail, some of it not so nice, some of it looking official, etc ... to tie them up for a while. Their legit mail will be commingled with all the trash mail. Use fake return addresses too.
