I'm a Human!
When people start spamming their channel links on others videos, and do sub4sub, then their channel has no good reputation. Using deceptive titles, tags and thumbnails is pretty annoying and I hate such channels.
YouTube channels that gets water-downed due to other projects (Movies, TV Shows, etc.) the YouTuber has taken on. Smosh, EpicMealTime, and I guess even Fred would be examples of this.
I wouldn't necessarily call it a "bad channel" but their channel seems more like a promo to watch their content elsewhere.
