" a problem person who keeps trying to create improper profiles by repeatedly slipping in their instant messaging contact information"
That made me think the OP is referring to the feature allowing unlimited members to review/approve profiles. Hitting the "Problem" button is supposed to flag those for review by an SLS staff member.
Aside from those with outside contact info, we've noted several that use a phrase that makes us suspicious that they are not legitimate profiles. i.e. scammers or escort services, etc. We hit the "Problem" button on those too.
Identifying the IP address thing is above our paygrade and we're not sure about paygrade the SLS staff members who get the Problem profiles.
