Oh yeah, I just found out about something cool.
In case you guys didn't know, a few months ago Nico Nico implemented a new policy where they would block videos with more explicit content to be viewed outside from Japan. This affected to a lot of gachimuchi videos. Anyway, there's now a browser extention which helps bypass that block

The addon is part of a new project to catalog YTPMV and Otomad so it has a few features related to that but I just use it for the geo block thing, it's really useful.
