Thanks for the warning
I don't often check that account, so little real traffic, such a tsunami of spam to a common name. I see it there now.
I think that warning is related to the expiration of the security certificate for a few hours yesterday. We were technically "unsecured", though I don't know how dangerous we could ever be. When I googled "habitablezone.com", the first item was a nice post by mcfly about Justin Trudeau.
Sorry you've been playing the role of human pinata lately. I can only hope that yesterday's resolution of the Republican primary is going to provide something fresh to talk about. The rut of sort of half-heartedly beating on each other might end soon, I hope.
So now you know: Trump's your guy. Happy about it?
