Long time reader, first time poster. I'm typically fairly reserved and don't really participate in community discussion, but today I do terribly need the help of the community. There's a man that's been harassing my wife and I via iMessage, and it's a person that we've had a difficult past with. Without going further into detail, he brings up troubling memories and stirs up all sorts of negative emotions between my wife and I. This has been causing constant stress/rifts in our marriage. I have tried blocking him through iOS7, and while this works just fine on phones, it does not register on OSX itself. So messages get through regardless. We cannot stop using iMessage all together, as we have many, many elderly family/relatives that use the service, and cannot have them all switch to something different. I've called and asked help of Apple support, but to no avail. I've come to this board looking some kind of solution, maybe if I mess with some internal files of the Messages app? or even a script perhaps that will block any incoming messages from this particular person. I'd really, really appreciate any and all help. Thank you.
