On July 9, 2015, the history website and podcast Damn Interesting posted an open letter titled "A Special Note to the Writers at The Dollop", accusing Anthony of plagiarizing Damn Interesting's original content for use on The Dollop. The Dollop subsequently deleted the offending episodes from their website and immediately established a website to cite their sources. After this incident Anthony has ensured that all episodes are appropriately referenced, and all the research and writing for new episodes is done by himself and others specifically for The Dollop.
