OK, so here's the deal. On the Sean Cody website, there are only 42 videos available from the first 7 years 2001-2007. A lot of those videos are solos.
all videos from 2008 were completely deleted.
There are 29 videos from the next 5 years 2009-2013.
all videos from 2014 was also completely deleted.
So, from the first 14 years of sean cody, we have less than 100 vids.
Baring a few small gaps, the videos past late febuary 2015 are still available. I don't think it's a coincidence that whispers of a Mindgeek aquisition were happening in January of 2015.
Exclusive: Sean Cody Acquired By Mindgeek/Manwin, A.k.a. the Same Company That Owns Men.com - TheSword.com
Also, The Pornhub scandal and news firestorm happened in early December of 2020, while Sean cody began deleting their vids a few weeks after.
It's very obvious what happened, The timeline lines up too well. The scandal spooked mindgeek, and they realized that the old sean cody vids either didn't have the right documentation or the documentation was lost. So, they bit the bullet and deleted all the vids to make sure to be safe and not sorry.
