I have not used the administrative functions of xenForo so I do not know if cleaning up spam bots is already something so quickly and sufficiently done with xenForo functions that this add-on would add little benefit.

Here is a screen shot of the the "One-touch Ban & Clean" option included in the drop down when I click my user name:
Of course, I cannot delete myself because I am in an protected user group, and because I have been registered for more than 2 days (both editable options in the AdminCP).
That being the case, I will use as an example a new account to show the screen that results when I click the "One-touch Ban & Clean" option:
The first sentence shown in the screen shot above included the user name and user id, but I cut that out.
This feature has made cleaning up the spam bot who appears once in a while a piece of cake. Would a feature like this be a good addition to xenForo, though?
