For those looking to skip in-video ads and other annoyances, this extension is awesome. Almost every video I watch now has segments that are seamlessly skipped.

For those looking to help out and submit segments to the database, this extension is a nightmare. In just a few weeks of doing this, I had multiple "VIP" users of the extension stalk and harass me on social media after I was quick to submit segments on new videos in their "territory" (i.e. large channels). The extension provides a submission "leaderboard" that drives this toxic behavior.
