Find out who approved new users?

[jnrdavo]

is there any way to find out who approved a new user?

I've been getting a bit of spam lately, and we only have three users who can approve new joiners...

None of us remember accepting the spam ones, so it's a bit of a mystery..

I'm thinking either one of our passwords has been compromised, or they have worked out a way around the 3.6.8 security...

Any help appreciated (maybe there is a mod that I can't find that will store the 'approver' name).

More on this... I'm getting spam from 'users awaiting moderation'....

Any help? I'm assuming that I have something wrong in the groups to allow this and will double check.
