From the link provided I read it differently, and didn't see anything regarding specifically "sps advertising"
quote-
Current approach *Pornographic content is generally permitted on Twitter, and it’s challenging to know whether or not sexually charged conversations and/or the exchange of sexual media may be wanted. To help infer whether or not a conversation is consensual, we currently rely on and take enforcement action only if/when we receive a report from a participant in the conversation.
Updated approach *We are going to update the Twitter Rules to make it clear that this type of behavior is unacceptable. We will continue taking enforcement action when we receive a report from someone directly involved in the conversation. Once our improvements to bystander reporting go live, we will also leverage past interaction signals (eg things like block, mute, etc) to help determine whether something may be unwanted and action the content accordingly.
