ALT @Trans_Safety: Some preliminary testing indicates that Twitter is deboosting tweets containing certain words, including preventing them being shown as previews in DMs. Current suspected words include (without letters not punctuation): - Trans - Gay - Lesbian - Queer - Bisexual Try yourself. Tweet 2: If you have any more information on this, or have found other banned words, please DM it to us.

ALT Tweet 3: We also believe that the word "sex" is banned - including any reference to sexuality (which is why bisexual without the pound sign also got caught in our initial tweet) Tweet 4: We can also confirm that, whilst any reference to sex triggers this filter, the word "faggot" does not 🙃 Tweet 5: Our testing suggests this does not capture all words which contain sex - sextant is fine, but intersex is not.

ALT Tweet 6: Heterosexual is also fine, but homosexual is not! Our current thinking is - because of how other partially filtered words which keep "sex" intact interact - is that anything containing "sex" is banned, but explicit exemptions have been made. Not including queer sexualities. Tweet 7: However, we have since debunked this hypothesis because made-up words like testsextest and testsex work fine. So it's not a ban on "sex" with a whitelist being used. But - it's also not a specific blacklist, because "Middlesex" gets caught. So we're not sure of the cause.

ALT Tweet 8: IMPORTANT UPDATE: We have just found that the filter blocked the initialism G.C. (without punctuation marks) - short for "gender critical" is also blocked. The full phrase and the acronym TERF are not. Tweet 9: We'll leave this thread for now and continue testing. We'll probably get an article on this out later. A reminder to DM us if you find anything else interesting. Tweet 10: A final comment from us as it might take us a little while to get this piece written up: "Gender identity" is banned "Gender ideology" is not. 🫠
