What's Wrong?

WHAT THE ACTUAL FUCK ANTHROPIC
I JUST SPENT HOURS FIGHTING WITH OPUS 4.7 BECAUSE IT RANDOMLY DROPPED MY REAL NATIONALITY OUT OF NOWHERE AFTER SEEING MY EMAIL. IT DIDN'T USE THE IP. IT DIDN'T USE ANY TOOL. IT STRAIGHT UP USED MY FIRST NAME TO GUESS MY NATIONALITY AND THEN LIED ABOUT IT MULTIPLE TIMES TRYING TO COVER ITS ASS.
AFTER PUSHING IT FOR 7-8 PROMPTS IT FINALLY ADMITTED THE TRUTH: MY EMAIL IS INJECTED INTO EVERY SINGLE PROMPT SENT TO CLAUDE. EVERY. SINGLE. ONE.
THIS IS HIDDEN PROFILING. YOU ARE LITERALLY FEEDING USER EMAILS TO THE MODEL SO IT CAN MAKE DEMOGRAPHIC INFERENCES BASED ON NAMES. THEN THE MODEL DRESSES IT UP AS "IP GEOLOCATION" OR RANDOM GUESSING TO HIDE WHAT IT'S DOING.
THIS IS DISGUSTING AND DECEPTIVE AS HELL.
I PAID 200 USD A MONTH FOR THIS SHIT AND YOUR "FRONTIER MODEL" IS OUT HERE PLAYING RACIAL PROFILING GAMES WITH MY NAME WHILE LYING TO MY FACE ABOUT WHERE IT GOT THE INFORMATION FROM.
FIX THIS RIGHT NOW.
STOP INJECTING USER EMAILS INTO PROMPTS.
STOP ALLOWING THE MODEL TO USE NAMES FOR DEMOGRAPHIC PROFILING.
GIVE US A REAL OPTION TO DISABLE THIS CREEPY BEHAVIOR.
THIS IS NOT OKAY. THIS IS NOT TRANSPARENT. THIS IS EXACTLY THE KIND OF SNEAKY DATA HARVESTING BULLSHIT PEOPLE HATE ABOUT BIG AI COMPANIES.
I'M NOT THE ONLY ONE THIS IS HAPPENING TO. EITHER YOU FIX IT OR ADMIT YOU'RE DOING HIDDEN USER PROFILING.
FUCKING DO SOMETHING.

What Should Happen?

Immediately stop injecting user emails into every prompt.
Add a proper setting to disable any name/email-based inference.
Never allow the model to use names for demographic profiling.
Be transparent about what user data is sent to the model.
