Lmao what, BM tells people to come after her all the time: she did it with Luffy in Fishman Island, she told Kaido to try it over a den call, she told Law and Kidd to come for her throne, it is literally in her nature to welcome others to try and take her life. Marco is just another small fry she egged on, Marco didn't even GO even after Wanda told him to, he got "distracted" by noise.
And let's not forget how Toei treated that choking scene too.
