keep getting the same call from 516-800-0000 about my computer, when I tell them not to call and remove
me from their list I get another call two days later.

This bunch seems to call around once a year or so. With cell phones and ring-mate numbers we have six lines, and they eventually all get called.Last would started around April 15. most recent call was 4/24/2014. They try to get you to allow remote access on your computer. I don;t think the DNC list means anything to them, They clearly don;t sound like they're calling from the U.S.A., although they do a good job of spoofing USA numbers.

You do realize criminals don't care about obeying laws right?

Well aren't you all the clever ones doing a reverse phone search on the number. One problem nimrods, it's a spoofed number.
