What you mentioned about the change in comments from genuine to the other types overtime, I also noticed on my posts after reaching close to 1000 followers.
I am glad you found my post entertaining - when I make posts about issues I try to add humor to them to lighten the conversation :)
Hopefully these undesired comment types will eventually be a thing of the past - but until then, I simply plan on upvoting/rewarding those who put in the effort to leave a genuine one :)
Thanks for your Genuine Comment! :)
