兄弟们，家人们，我太难了，罪魁祸首是@CuiMao 前男友，他们家 AI 写的 Bug ，对我们的反诈事业，造成了重大损失。前几天还跟朋友嘚瑟 MXGA 用量大，但多亏 Cloudflare ，实际成本才几美元。今天突然收到账单 $200+，D1 单项 $198。review 发现是查询 Bug，用量干到 1400 倍，超了免费额度计费爆了。🥹 pic.twitter.com/66SgNAlxv8

感谢赛博菩萨 Cloudflare 对我们反诈事业做出的重大贡献，上个月由于 Claude Code 写的 MXGA 代码 Bug 导致的数据库用量爆炸，让我产生了 $209.37 美元的天价账单。发了一个工单，描述了项目的性质之后，Cloudflare 给了豁免。🫡 瑞思拜克 pic.twitter.com/IT0qRMx2b9

D1 migration: the author reports a $911.56 charge after stopping the job.
@m0xandrew says a hobby-project D1 migration reached 8,274% of a budget alert, so he stopped it and requested a one-time waiver. He later reports a $911.56 charge, closure of the old case and opening a new support case.
Jason Silberman: an approximately $1,000 AI-billing dispute, later reported resolved.
@_jasonsilberman reports an invoice around $1,000 with AI usage rows he says were duplicated and already prepaid. Cloudflare personnel reply, including Matthew Prince, who says the case was escalated. The author later says the issue was resolved.
