I haven't quite confirmed this (I only just checked my email a few minutes ago), but it looks like our group was spammed this morning with an email containing nothing but a link to what appears to be a Russian website masquerading as a CNBC News affiliate. I strongly urge you NOT to click on that link! I'm not sure what will happen, so your safest bet is to just stay away.
I've contacted the sender and warned him that his computer may be infected with some sort of malware. I also warned him that if he sent the link intentionally, he will be banned from the group if it ever happens again.
I hope that's the end of this. Let me know if you have any more problems!
Sorry for any convenience this may have caused.
