XF 1.2 Do not show 'Awaiting Activation' accounts in 'Users Online Now' area

We're currently having some spam issues which we are working on.

For the time being, is it possible to stop these spam users (who will be in the 'Awaiting Activation' state, from showing in the Users Online Now box?

It can look pretty bad if you've got a couple of genuine users online and then a tonne of spam bots which obviously spammy names.
