Sorry, late. But the female author's username on the Official Manics site was 4Real03 (or something close to that). She was really young back then, but I don't think that fully excuses the abuse she dished out. Plus, even all those years ago, she seemed to have an axe to grind with the band because I distinctly remember wondering why she was there if she hated them so much. I also remember her because I was one of the people she came after.
Anyway, as for Sean. I knew he had a Facebook account which I thought was very strange for a guy in his position. An official FB page, sure. Loads of musicians would have one of those. But an actual account, adding people and joining groups dedicated to their band ... that was definitely weird. I assumed it was a fan pretending to be him (there was one for James Dean Bradfield for years, at a time when we all knew James barely knew how to switch his mobile on, god love him). But then people within the fandom who're "in the know" verified that it was him.
But if that account is now deactivated, hopefully it's because he's over his midlife crisis and settling down with his new partner? But it's still crappy if women were being used by him - I make no excuses for that.
