Is it possible to capture the user who is trying to access your account (when there is a failed log-in attempt) by using the front camera of the device if possible? and the image captured will be sent directly to your email address that is associated in in your account. Some security app supports this feature and I don't know if SMF or any website supports this feature but this would be somehow a cool one. But will be useless if the device's camera is covered.

As far as I know only applications are capable of this kind of feature so it can be added as security feature once there is a official app for Bitcointalk   but still a bad idea since application softwares are reversedengineer-able or can be modified to use for phishing.

But just in case, I have some tape on it as a physical confirmation that it's not doing this.

I think spying on users fits in the same category as KYC on Bitcointalk:

I don't think I saw this.

Not critical but it would be nice if the Report to moderator page, came up in a separate tab. The same way the Merit page does.

It's a small annoyance when I go to report someone in the middle of reading a topic then I have to go looking for them. It's small and easily doable if I'm not mistaken Theymos made the change rather quickly when VOD suggested it for Merit.
