Reddit will delete anything remotely controversial if it contains referenced facts. They banned and deleted my account for simply stating the 5th amendment prohibits requiring incriminating yourself to exercise a right. An Ivy League educated lawyer dug up the comment one year after I posted it, told reddit I was distributing illegal legal advice, and had my whole account nuked.
I got suspended for criticizing the state of Israel’s treatment of civilians in occupied territories, but they didn’t delete my account, though I stopped logging in after a week. (Logging in retains your subscriptions). I've seen plenty of similar comments to mine so I assume it was the work of some oddball who I responded to that has an connection to somebody who works there so they could pull some strings to suspend my account.
At the same time Reddit was hosting Arabic speaking subreddits with communities that openly support terrorist groups.
Considering that some of the content may well be illegal in a few EU countries, I was surprised Reddit does not more proactively nuke it to protect themselves.
