Is there any way to mass select unwanted members for their deletion?

I am facing excessive registration of spammers and I would like to have them deleted from my members list. Ideally, I would select them by ticking boxes (or the whole column) and delete them in two clicks. I am unsure how to achieve it at the moment.

 

In AdminCP - Members - Member Settings - Registration enter a number of days in the Remove unnvalidated members box and that will remove them automatically after a set period of time.

Thank you, that is very useful, still it would be nice to have multiselect option available for deleting multiple users like spammers.
