Accuracy Alert!

Based on the provided sources, the claim that the "Dark Brandon" moniker was first used to mock Joe Biden before being adopted by his campaign appears to be largely accurate. This term originated as a detrimental meme created to caricature Biden, with sources such as www.reddit.com, www.dailyo.in, and en.wikipedia.org confirming its initial use by critics. Eventually, Biden's campaign began using the "Dark Brandon" meme, as mentioned in articles by www.truthorfiction.com and medium.com. Thus, the sources confirm that "Dark Brandon" was used both as a means of ridicule and later, as a part of Biden's campaign.
