You don't need an email at all to post on 4chan. You don't register to use 4chan or post on 4chan. The only logins are for staff. People are making up and spreading rumors that don't even know how 4chan works.
Heard about this just a few hours ago, and have been laughing ever since. This is going to be brutal, there are people who registered with .gov e-mail addresses. As the use of 4chan has been cited to me as potentially disqualifying people seeking security clearance for government, police, or military careers, this hack single-handedly has the potential to torpedo thousands of edgy bois in one fell swoop.
Keep dreaming. 4chan only has registration for staff. All you have to do to post on 4chan is a captcha. Did you even read the article? It addresses the .edu and .gov rumor as false.
I've been told that for clearance above reliability that social media use becomes an issue. 4chan was specifically cited to me by the person with whom I spoke. I'd assume that this means any/all alphabet government agencies, but Army was all that I heard about specifically.
"Do you browse or use 4chan?"
"No."
"OK, good, because you weren't advancing beyond this stage if you said yes."
