An error message appears saying "The following are not allowed: no zionist, no zionists" when users try to add the phrase to their bios, but any number of other phrases about political and religious preferences are allowed.
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.
