The whole "The_Donald was a FBI honeypot" is a pretty strongly persistent urban legend. And obviously false. Surprises me how many people thought that was legitimate.
Ask yourself: Shouldn't there have been results sooner? Would FBI (or whoever) have left an obviously dangerous forum open for honeypot purposes for years and years? If this really was a honeypot operation, wouldn't they have made arrests as soon as they could? And if this really was the case, shouldn't we have the details by now (FOIA requests or whatever)?
Of course not. US law enforcement would have immediately involved themselves if there were any credible threats posted there. But they don't really do much about festering pits of far-right radicalisation. It was left open with the full approval of Reddit admins. Can't really claim ignorance on their part either.
The Honey pot conspiracy is fake. But Hillary Clinton did use her influence to prop up Trump early in the election thinking that he would be the easiest candidate to face. And I can see reddit being a part of that plan.
Hillary was hardly alone in that. Can't find the exact video, but the point of the video that Jimmy Kimmel platformed Trump, with the guise that the show was "apoliticial". The video argued that that was not the case. The broader argument: "If you're atheistic, you denounce the existence of gods. If you're polytheistic, you acknowledge the existence of multiple gods. Now, if you acknowledge the views of all political candidates going your way, you are not apolitical. You're polypolitical."
