Third party blocking service seems to already be set to intercept calls from this number on May 2, 2016.
We got a call from this number with CID name "V50211522100587" the morning of May 2, 2016. It rang only once and did not call back. Our third party blocking service (rhymes with SlowNoHobo) intercepts calls with caller ID numbers on their blacklist after one ring, so we assume they've already blacklisted this number.
I'm posting about it here because there weren't already lots of reports of nuisance calls from this number when I looked it up. Not that using "V50211522100587" as the CID name wasn't reason enough to avoid answering this call, haha.
