Antisplog and buddypress spam users

Hi, i'm using the anti splog plugin (and i've just renewed the subscription for another year) with a buddypress website. I've a lot of spam registration everyday, and the plugin works great. I've set that the users should be set as spam too (not just the blog), but there is a problem... all the signups stay in the activity list of the website, showing a lot of spam signup activity. Is there a way to remove them?
I'd even like to hide the spam users from the list of the members (and everywhere that members are used/showed)
