I added a real-time chat to my blog, people used it to attack me

A developer added a simple real-time ephemeral chat widget to their blog, only to have it weaponized when a Tailwind CSS criticism post went viral on Hacker News. Attackers used the chat for insults, impersonation, content flooding, and XSS injection attempts. The author describes the attack types, the countermeasures taken (word filters, character limits, patience), and key lessons: treat every input as hostile, real-time moderation is fundamentally harder than async moderation, and ephemerality reduces troll incentives by removing karma and history.
