Cheaters can't be get rid in this community completely but such act can be reduced in this community that even those who will practice that act of cheating will have to go through a lot and anyone being caught in the act will be punished.
Plagarism is once discussed in this community few days ago in this #pobstreet a topic suggested by @scholaris.pob.
He has been taking a full measures to catch all who are in the act of cheating by plagarism and punishing those account by downvoting.
I also noticed that those act are too much especially in proofofbrain community.
But there has to be a perfect way to eradicate it entirely
