I'm sorry, a picture of a non naked dude shouldn't be marked as sensitive without a clear ideology.
Either way, my intention was to say: you can disable these quality filters, Twitter isn't forcing you down an ideology with no opt-out. On that note -- many of these are based on user reports: if accounts get too spammy they get put in "other replies", if they're regularly inflammatory they (might) be put in "other replies" + sensitive content, etc. But again, you can turn this filter off and see all replies together, media normally, etc.
