(This is not a joke)
Corrupted-Files.com is a web site that sells intentionally corrupted (or damaged) Word, Excel, and PowerPoint files.
Why the hell would someone want to buy a file that will not open?
To submit to a teacher/ professor. Sending a file that won’t open will allow a student to “meet” a deadline, while also buying them some extra time to actually finish the project.

Here’s how it works:

I came up with this exact idea about four years ago. However, by the time I thought of it, my “lazy bag of poo” phase was long past, so I never tried it. I also never thought of marketing the concept.
That’s… That’s an amazing idea XD
I know! Unethical yet brilliant.
I foresee a future where teachers are receiving a ton of corrupted files… then they will catch on.
Shocking!!
:D
Just imagine how many students are doing this scam.
