from the article:

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.
