Hover a thumbnail on youtube.com and click an icon at the right: "Not interested" and "Don't recommend channel"
< YT: not interested in one clickについてのフィードバック
Also added a comment to ENTRY near the start of the script to remind that those are classes, not id nor element names. That helps in hunting the root of future problems.
For future notice, change the element positioning to the following:
ytd-compact-video-renderer .${ME}[data-block] {
top: 36px;
right: 7px;
box-shadow: .5px .5px 4px 6px #000;
background: #000;
}
ytd-compact-video-renderer .${ME}[data-block="channel"] {
top: 68px;
}
The defaults are cluttered at the bottom of the thumbnail on recommendations, this spaces them evenly within the thumbnail.
