• Abstract: Online content creators spend significant time and effort building their user base through a long, often arduous process, which requires finding the right ``niche'' to cater to. So, what incentive is there for an established content creator known for cat memes to completely reinvent their page channel and start promoting cryptocurrency services or cover electoral news events? And, if they do, do their existing subscribers not notice? We explore this problem of \textit{repurposed channels}, whereby a channel changes its identity and contents. We first characterize a market for ``second-hand'' social media accounts, which recorded sales exceeding USD~1M during our 6-month observation period. By observing YouTube channels (re)sold over these 6~months, we find that a substantial number (37\%) are used to disseminate potentially harmful content, often without facing any penalty. Even more surprisingly, these channels seem to gain rather than lose subscribers. To estimate the prevalence of channel repurposing ``in the wild,'' we also collect two snapshots of 1.4M quasi-randomly sampled YouTube accounts. In a 3-month period, we estimate that $\sim$0.25\% channels -- collectively holding $\sim$44M subscribers -- were repurposed. We confirm that these repurposed channels share several characteristics with sold channels -- mainly, the fact that they had a significantly high presence of potentially problematic content. Across repurposed channels, we find channels that became disinformation channels, as well as channels that link to web pages with financial scams. We reason that abusing the residual trust placed on these channels is advantageous to financially- and ideologically-motivated adversaries. This phenomenon is not exclusive to YouTube and we posit that the market for cultivating organic audiences is set to grow, particularly if it remains unchallenged by mitigations, technical or otherwise.

  Noisy channels are valuable resources for cryptography, enabling primitives like bit commitment and oblivious transfer.<n>We present a protocol for string commitment over such channels that is complete, hiding, and binding, and derive its achievable commitment rate.<n>The commitment rate coincides with previous results when the adversarial channels are the same binary symmetric channel as in the honest case.

  We discover that conspiracy channels can be clustered into four distinct communities comprising over 17,000 channels. We find conspiracy theorists leverage e-commerce platforms to sell questionable products or lucratively promote them through affiliate links. We conclude that this business involves hundreds of thousands of donors and generates a turnover of almost $66 million.

  This study explores differences in video production across 27 co-active channels on YouTube and BitChute. We find that the majority of channels use significantly more moral and political words in their video titles on BitChute than in their video titles on YouTube. In some cases, we find that channels produce videos on different sets of topics across the platforms, often producing content on BitChute that would likely be moderated on YouTube.

In comparison with mainstream content, conspiracy videos had similar levels of ads from well-known brands, but an almost eleven times higher prevalence of likely predatory or deceptive ads.

  We show that exposure to alternative and extremist channel videos on YouTube is heavily concentrated among a small group of people with high prior levels of gender and racial resentment. Our findings suggest YouTube's algorithms were not sending people down "rabbit holes" during our observation window in 2020. However, the platform continues to play a key role in facilitating exposure to content from alternative and extremist channels among dedicated audiences.
