About 2 days ago I started receiving chat invitation spam. I get a new "chat request" about every 4 hours now always from a random spam-ish looking aol.com email address [latest one is: firstname.lastname@example.org]. The requests get a notification and create a notification sound similar to a text message. When I click the notification I get the following message box: Accept invitation NNNNemail@example.com wants to chat with you. Will you accept? I have the options to accept, cancel and block. I block, and the requests keep coming. Anyone have any idea how/why Im receiving these and how to stop them?
