Is the Matt 11k System a Scam?

I keep getting robcalls or voicemails from Matt regarding the 11k system located at 11ksystem.com or www.elevenksystem.com, asking me to check out 11k.com for a money-making opportunity. I have received two calls today and before that, I have received similar calls from the same Matt from different telephone numbers. The telephone numbers are +7-755-712-290, +7069489717, 201-649-6282 and a 602 number. He sounds very legitimate but the fact that he's calling from different phone numbers does seem like a scam. I don't see how much work you can do online with the 11k system to make $2,375 per day.
