There ARE predatory types in AA meetings, who try to pick out vulnerable newcomers.
The best defense is to have a good sponsor to consult for guidance.
Some AA groups are better than others about confronting those who use the group for "Thirteenth Stepping" (what trolling for newcomers is called). My ex-husband had to confront a guy who was doing that in their group (he'd already been kicked out of other groups for doing the same thing) and when he refused to see anything wrong with his behavior, he was told he was no longer welcome in the group. That's how things should work--a group conscience should decide how to handle it.
Not all groups are that conscientious, though. Either way, sticking with the strong women in the group will be to her benefit.
