A new trend has emerged on YouTube where ‘scammy’ channels facing a ban for copyright infringement appear to evade penalties through the use of sexually explicit content. Questions remain, but evidence does suggest that a loophole is being exploited. By avoiding termination for copyright infringement, these channel owners may be able to protect their linked AdSense accounts.
Tldr: Getting done for copyright you lose your income.
Getting done for porn, they just close your account so you can keep going.
