Reddit has almost 20 years of comments.

You could certainly argue that it's less true now that there's legitimate people commenting, but there are years old threads on there with very helpful and valuable information that you can only really find via some incantations of Google search.

		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.
