When I clicked to respond to a scamming target, I got a captcha challenge.
After completing it I clicked to respond again.
It consumed 3 nerve, but didn't move the bar at all.
It is listed in my log as successful too.
21:56:25 - 20/11/24 You used 3 nerve successfully responding to a Tax Scam target.
I think it's worth pointing out that the only possible result would have been "hesitation" which wouldn't be considered successful anyway.
