Fight back? Those that buy upvotes cant really "fight back" or they wouldnt need to buy upvotes. They would just selfvote.
Its not about fearing retaliation its about sharing an opinion, sending a message:"I think this is wrong what you are doing".

ok i see your point.
Also I didn't check the author's auto voting for that much, but i am sure he is not the only one doing it...

Well I don´ t know tbh, I just know that some abuse the downvote and it makes people fly away to other platforms.

Downvotes, as I said impact also curators rewards

And why small users do not have the opportunity to downvote and also impact rep and reward ? that is what I call the unfair part

Even on youtube downvotes do not impact the earnings, seems to be a healthy platform though
I hope you see my point too

Almost 4am here, I will read further comments and reply after a good rest :)

I don't autovote.

Sorry, I am NOT english native so I make errors, I meant self voting

You mean flagging a dung post which got 400 is wrong? You should take a swim
