Nothing says "professional business relationship" quite like ransomware-ing your own client's website. Developer delivered the site, client ghosted on payment from "Joseph Smith Furniture," so now the site's held hostage with a polite little message: "If you need access, pay me." It's the freelancer's nuclear option—turning the entire website into a payment reminder. Technically genius, legally questionable, morally in a gray area the size of a production server. Sure beats sending invoice reminders that get ignored for six months. Pro tip: contracts with kill switches are great until you're explaining to a judge why you implemented your own version of "pay-per-view" on someone's business site. But hey, at least the services were delivered.
