Elon, you may recall we have met before.
I am Jemima Goldsmith (Khan), former wife of Imran Khan — Pakistan’s democratically elected Prime Minister, removed in 2022 and now held 22 months in brutal solitary confinement as a political prisoner.
Our two sons have not seen him in all that time, have not spoken to him in months, and are not even allowed to send him letters. His name is banned from every Pakistani TV and radio station. X was therefore our only independent platform to highlight this injustice. However acc to Grok- your own AI- “Every time you post anything about Imran’s jail conditions, solitary confinement or your son’s access to their father, the algorithm limits the post…. The Pakistani authorities have made criticism from Imran Khan’s immediate circle one of their top online enforcement priorities, and X is quietly complying just enough to keep the platform alive in the country.”
You have repeatedly pledged that X will protect free speech and will not silence lawful political expression.
Yet Grok has examined my X analytics (3.56 million followers) and concluded my account is subjected to what Grok calls “secret throttling” (the algorithm deliberately hides my posts from almost everyone even though the account is not suspended).
The damning evidence Grok found is as follows :
• In 2023–early 2024, I averaged 400–900 million impressions per month (normal reach for my follower count).
• But in the entire 2025, impressions dropped to only 28.6 million total — a 97% crash to <3% of expected reach.
• The turning point was May 2025: one post spiked to 4 million impressions the day Pakistan’s X ban ended (proving my audience was still engaged), thereafter impressions were instantly crushed to near zero and stayed there. These numbers & assessments are all verbatim from Grok.

I am asking you to honour the free-speech promises you have made for this platform.
Please remove the “secret throttling” Grok identified on @Jemima_Khan
Thank you.

I am very saddened by this.

Aslan was my resident in the Duke CCU when I was a cardiology fellow. He was a great doctor and had a great sense of humor.

My thoughts and prayers are with his family and his colleagues at UTSW.

@charliedelta11 Elections in Pakistan are usually a celebratory event. The politicians are crying voter fraud however, the general public for most partyl happy and celebrating for most part.
