hello all, I am watching some channels on youtube and wondering, what are that "non sense" comments (for example here: youtube --- watch?v=UbX1UM_NoLY ) Samantha Cameron: 4vrf vrgh .. etc. Are those comments made by some bots? Do they help rank videos? Another question... are theese #tags comments posted by author helpful? I am wondering how new channel could have so much views and succes in a short time...I want to find their formula, but my reasearch was not so succesfull. Thank you so much for answers!
