I worked for an Australian insurance company and we physically DDOSed a poor man's real mailbox with printed policy documents as we used their address during e2e testing and we mistakenly didn't put a testing flag somewhere.
Our CTO had to personally apologise to him
This sounds hilarious, how many physical items are we talking? Like his whole front porch full up of contract boxes?
The documents pack is like an A4 folder 1cm thick. He received close to 100 in one day. Enough for his mailbox to get full and for the postie to dump most of it on the lawn
