I would combat that by not having a Facebook page ( I don't), or at least setting the privacy at the highest level. I would then think about the balance between the single hit / long term prospect before taking a lot if money from a machine at a time when it's on the radar.
And on here, I just don't mention what I'm playing. Why do you? First Seal The Deal, and now this.
It just seems like a no-brainer to me. Why are you surprised you are known to "steal" money from machines when there are sites like this which anyone can visit? And you then post on this site exactly what you're up to?
It's kind of like posting a photo of yourself doing something you shouldn't, and then being surprised when you get what's coming to you. As an extension of the social circles that exist, I'm sure you're not informing too many people when you post on here. But it is pretty pointless isn't it? And it was especially dumb of him with the Seal the Deal thing, as this was way before they were chipped (last year I believe).
