from what i hear on arfcom, the WSJ wanted to make sure the people who commented are real. i deleted it.
I'm not on arfcom, and hadn't heard anything about it.
Figured they got my email from me doing some free sign up thing to view an article, which was the only reason I was willing to click the link.
Soon as I saw the comment they were asking about (which I recognized as mine), I started to get suspicious, but got kind of freaked out when they were asking my name and email address.
Read the email closer, at the end, they were going to ask for my phone number and if I'd be willing to be interviewed.
By the way, how did they get my contact info? FOIA request? I started doing searches after I got this email, and found my comment with my name on the bump stock ban, but couldn't find my email address that I used.
