- Twitter monetizes their platform with ads.
- Twitter will not sell ads to porn or explicit adult enterprises.
- Twitter ( and all ad sellers notwithstanding CPC) make money selling ads -- not by users clicking on the ads.
- If Twitter loses 25% of their 'porn' traffic their CTR rate impact on the ads they sell would be minimal.
That's why -- porn is excess baggage for Twitter.
Make use of Twitter's traffic while you can but only a fool would build a long-term strategy on a platform they do not have a firm deal with or they do not own outright
