That "paper" is atleast 5-6 months old and it has been disproved many times.
Not sure what's up with those polo fud campaigns.
I'm not affiliated with any exchance or anyone that might be interested in a "fud" campaign.
I wonder where you see my paper has been disproved ? Except from the reddit post
"Poloniex is secure", which is to be considered carrefully because from Poloniex itself, I can't find any other.
So basically, to answer your question, there is no such fud campaings, only truths.
