The thread has gone a bit off track. The OP's intent was to get a response from the developers to clarify the Terms of Use regarding the naming policies. Not whether the sentence written and/or guild name was funny, wrongful or disgusting. It's interpreted differently depending on who reads it. Although whether it should be a bannable offense or not, It's still not our decision to make sentences like these prohibited, it's up to each individual Game Master and how they interpret the Terms of Use and the sentence in question.
The guild name "Sapped Girls Cant Say No" can be interpreted differently, to such an extent that even Blizzard allows it on their servers. It's currently being used in both US and EU Warlords of Draenor, but one has to point out that Blizzard is nowhere near as strict when it comes to the naming policy as they were in 2006.
The sentence would most commonly be translated into "Incapacitated/Unconscious girls can't say no to sex" If one were to use this as a Guild Name, would it be a bannable offense here on Nostalrius servers? Most likely yes. Would it be a bannable offense on Blizzard servers? Definitively yes.
