4chan is also incredibly infamous for trying to take credit for things they never did. 4chan used to be filled with some legitimate hackers who did some pretty awesome shit... then all got hired by the government and now likely work for the FBI/CIA/NSA. 4chan is just a bunch of script kiddies now at best, and at worst they're that friend who hops on your computer, gets on your facebook and posts "HACKED LOL!"
Ever since all of the real hackers vacated 4chan all of the kids keep trying to take credit for things they didn't do because they exist in the shadow of their predecessors who they can't live up to. Anyone who believes anything they're trying to take credit for either doesn't know about 4chan's history, or if they do know about it, are being incredibly dumb for believing them.
They're getting their 15 minutes of fame from Trumpkins believing them, then they'll fade back into obscurity for having accomplished nothing of value to the world.
