Hater’s love to hate but at least they do serve the purpose of at least letting you know someone is paying attention. 
It’s just the way of the Internets that when the opportunity to voice one’s opinion is given as an option then you will always have those who feel compelled to tell you how you are doing it the wrong way.
As an artist in general though I do tend to revel in the behavior of others that through my actions has motivated them beyond the posting of a few cruel words and be it good or bad that should be the intent of anything considered to be a form of art.
In the mean time if they are out to troll you troll them back with kindness and as the bully they are will generally back down due to your inability to serve their needs.
