No need. They are likely addicted to one site or another....plenty of FB/Twitter etc addicts out there.
Reminds me of the first time I mentioned to my daughter that I was a mod here. She looked at me strangely and asked me "Just how much are you on there? Do we need to do an intervention?"
I told her no. I just help out. But if I need an intervention then so did she from FB. We laughed and that was it.
