There's more than that. She was on the verge of exposing Chinese intelligence surveillance methods/technologies. The Shenzhen authorities know her well and were relatively lenient, but the moment she touched upon the intelligence area, she attracted the attention of much more paranoid security officials. Those officials then found out she had a Uyghur girlfriend and became even more paranoid due to suspected links with terrorism; those officials, after all, spent the 80s/90s taking bullets from Uyghur terrorists, so they are quick to jump to conclusions that Naomi is compromised and sends intelligence secrets to Turkistan Islamic Party.

I suspect these are much more of a reason to offboard her from social media than all the LGBT stuff, which she had already done for years.

Source: The Daily Mao on Twitter, who said he physically spoke with her half a year ago. Naomi said she's fine, she's just not allowed to have a public social media presence. She's very lucky not to have been thrown in jail for national security/terrorism reasons, especially given how paranoid the security officials are. Perhaps the Shenzhen authorities put in a good word for her.
