Nothing says "professional business relationship" quite like holding a website hostage with a ransom note plastered across the homepage. The developer didn't get paid, so they did what any reasonable person would do: restrict the entire site and threaten data deletion. It's like burning down the restaurant because they didn't pay for the kitchen remodel. Sure, non-payment is frustrating, but publicly nuking a client's site is the nuclear option that guarantees you'll never see that money AND you might get to explain this to a lawyer. Pro tip: kill switches and escrow agreements exist for a reason. Or you know, just take the L, keep your reputation intact, and move on. But where's the drama in that?
