Malwarebytes isn't letting me go to their website, the "we blocked xxx IP" comes up. The game has changed, if a few major sec companies blacklist you, you are toast.
A friend of mine at MS said the same thing, the IT department blocked the IP.
Yep this is blocked under "Pay-to-Surf" at the company where I work. Not sure what security provider they use, but this isn't looking good for a YC backed startup...
