There are increasingly many users registered in a 50km circle around my house, most of which located in Vitoria and Vila Velha. I've noticed that most of these never have done any edits, and have no information at all on their profils. It is probably thousands and thousands of these. Does the administration any way of checkingnlast login of users? That way one could install a filter, or in some way remove, users that only have created their accounts, but not contributed in any way.
