Wasn't Tarantula in fact hired to kill Babs, but rather than kill her Tarantula took it upon herself to create a wedge between them because it would make Dick crazy or some such BS? (I'll admit, it's been a while since I read these issues - in fact I try to forget they exist - so I could be wrong.) Sadly though, I can't help but think that if Babs wasn't fronting BoP at the time, Grayson would have in fact had Tarantula kill her off.
Also it saddens me that she is not more aware of how what she wrote, re: the sex, comes across, especially as she was a victim of abuse herself.
