Over the last week or so I have gotten a lot of "has accepted your invitation" messages from profiles I have never seen before. It has been over 6 months since I used a mass invite list and a lot of these profiles look strange - no last name, very little information, or no information at all some with a LION designation. Has anyone else experienced this? It is like someone is gaming Linkedin. I hate to see it, and it concerns me. Any thoughts?
