Let's see:
-False titles and thumbnails.
-Long intros.
-Annoying music in intros (IE dubstep)
-Bragging about how much you make on your videos, which includes possessions (IE fancy car, large TV, etc) bought with said money.
-Excessive use of jump cuts.
-Asking for like/sub at the very start of the video.
-Censoring vulgar language. Stuff like "f**k" and "s**t".
-Keywords in the description.
-Turning off comments/ratings.
-Making a gaming channel for the sake of another revenue stream.
-Prank channels. They just seem...fabricated esp. those in public.
-Overproduction/"Plastic" look and feel.
