Hey mitchy, technically speaking there's no downvote button there's a flag button. IMHO this should be used pretty sparingly for only the lowest quality stuff, spam, etc.
I was doing an experiment playing around with some different types of posts. I did one post, a little photo essay about the sexiest woman on Instagram, honestly not my best piece of content but like I said I'm experimenting with some stuff to see what people are looking for and honestly it's the same type of stuff I see other similar posts making $50 for yet someone downvoted me on that as well as another post.
I'll totally admit not my best two pieces of content but imho hardly downvote worthy. If you follow @pawos advice you can sort through basically the entire history of your upvotes and downvotes and see who upvoted you and who downvoted you as well as a lot of other activity on your account
The guy who downvoted me has actually resteemed me in the past so I can't say someone is out to get me, but still personally something has to be pretty terrible for me to flag it, I personally don't agree with the downvote.
yeah me too I never like to dis like on YouTube
