Well said! You are so right about the stupid comments.
I always like to look at the comments on all videos that I view.
Fortunately, it seems that the outpouring of the ignoratii can be quickly identified by their illiteracy -including sentence construction, spelling and punctuation (or lack of it).
As soon as I see any use of the following few examples of interchangeability (there are several others) I tend to move on;
Your instead of you are or you're.
There (or thier) for their.
Peddle for pedal.
Aloud for allowed.
Axel for axle.
To for too
Also the use of tired, worn-out, hackneyed, overused, and completely unnecessary expletives is another turn-off
It's also revealing how often these characteristics tend to go with the most ignorant, spiteful and generally insulting content.
