GFork

→ the program is case-insensitive
→ put a * in front of a word for wildcard (only in the blacklist!), it will find the word no matter its position in the username (example: *vevo)
→ you can choose the symbol to split the usernames (default is a comma) ('*' not allowed) (max 1 character)
→ you can enable/disable to blacklist channels by clicking/right clicking on '[x]' before the usernames *
→ you can suspend temporarily the block (to reactivate it just click on save or refresh the page)
→ it hides videos of blacklisted users/channels from recommended, search, related channels...
→ also from the playlists/mixes, but it doesn't prevent them from playing if the playlist is in autoplay
→ for both the new and the old youtube layout

* known bug with the new layout: when it's enabled clicking on '[x]' opens the video, so right-click it instead.
