Grindr won’t allow users to add “no Zionists” to their profiles, but allows any number of other phrases that state political, religious, and ethnic preferences, according to 404 Media’s tests of the platform and user reports.

Several users received an error message that says “The following are not allowed: no zionist, no zionists,” when they tried to add the phrases to their bios on Thursday. I tested this myself on a new Grindr account, and received the same error message. I was able to add “Zionist” to my profile (without “no”), however, and could also add any phrase I could think of: “no Arabs,” “no Blacks,” “no Palestinians,” “no Muslims,” “no Christians,” “no Jews,” “no trans,” “no Republicans,” “no Democrats,” and so on. “No Zionist[s]” was the only phrase that was blocked in my testing.
