You also got to remember that Baroque Works was a secret organisation where few knew who was within the organisation. Discluding Vivi of course, since she joined specifically to gather intel on who was behind BW, hence why she knew so much. Most probably didn't even know Robins face, only her name.

Also Crocodile only used her for his gain, and never trusted her to begin with. I doubt it was really a warm welcome
