Your art is fantastic and you should not be influenced by these comments.
From experience I will tell you that the best way to act is to ignore those comments and never respond. If he's just an angry person, he'll get tired soon and leave you alone. If, on the contrary, you believe that the motivation behind these comments is another and these users get some benefit, then they will not stop and what you should do is formally denounce the authorities.
Thank you for your comment, I believe there are some quite stupid kids that make the comments and someone that plans these mass following/defollowing movements to bully me, honestly I don't think the grand number of my followers agree with the bullying people, I am receiving some cool manifestation of interest by big influencers, but they are scared of reblogging my ai art too, and that's the point, the mass of ignorant people and the fear, I love what I do, and I would honestly do it even just for myself, so my important message here is:
THANKS FOR APPRECIATING MY ART
There's a piece on my heart on it 💫
