I have a similar story about the batch scripts I wrote in highschool to circumvent the monitoring software. Someone stole my script and made it out like they had wrote it. So in retaliation I added copyright notices to the comments and printed similar notices when the script was run. I even planned to rewrite the script in C# and distribute it as a binary.
In hindsight if that script was ever seen by a staff member I'd essentially have self-snitched.
