Looks like Admin is actually following our discussions. Correct me if I am wrong but I believe giving +Karma was unlimited before but now it is the same with giving out -karma (1 in every 100 hours). I was trying to give +Karma to all who reported plagiarism but I was only limited to one. I'll try again after 100 hours.
EDIT: New rule now is that you can only give a karma once in 100 hours. It does not matter if it is positive or negative.
I just gave +karma for all those who found plagiarism and posted in https://www.altcoinstalks.com/index.php?topic=62494.0
I also gave -Karma to all plagiators .And yes,you can do that every 100 hours again and again.
1 in every 100 hours is just meant for 1 person,i just shared 20 +karma and some more -Karma in 1 hour 
Thanks for clearing this up +1
Sent some +/- karma to users on that thread.
I hope we get more users to participate in trying to make the forum better.
Looks like some of my +Karma came from both of you. I'm glad to return the favor.
I granted +karma to those who reported plagiarized posts/comments and -karma to plagiarist.
If they (plagiarist) can grant +karma among themselves, I think it's just fair if we grant karma to those who will report.
Well,just coming back from giving weekly -karma for our well known plagiarist from reported site and guess what happend?
I also got some -karma.
There are some members in this forums,like yousufatik https://www.altcoinstalks.com/index.php?action=profile;u=32221
He has 5 referralss,all doing plagiarism,we all reported them already with proof.And all of them are giving each other +karma .Me giving them -karma last 3 weeks ,but their karma is growing even more and mine is shrinking
Someone must take some serious steps to stop this or good and honest members will go away.
I am actually thinking the same on plagiarizers giving +karma among themselves.
I also suspect a plagiarizer was responsible for the -karma that got recently. This must be the karma war issue that was raised before.
Let's keep doing our share and the higher ups will take care of the others.
How about Admin giving them a "plagiarist badge"
Or maybe creating a list of rampant plagiarist? Bounty managers can also use that as reference in accepting/rejecting a participant.
I personally see some newbies that are copying my replies and they are just adding some words to make it look
different. 
Giving them some kind of badge just what you said will be good but I don't think they will stop from copy-pasting
posts from other forum members.
Better report those newbies that you see. Those higher rank plagiarist also started the same practice when they were newbies.
I like the plagiarist badge. It may look harsh on the user but if its the best way to stop them , then so be it.
Yes, I will definitely report them from now on and today I saw some senior member copy-pasting my post and
just changing some of the words that I've used and it is really obvious that he/she copied my post/reply on a
thread.
Those plagiarists are becoming a real headache in this forum and they are really polluting this forum with their
ways of thinking and interacting.
And something that I've noticed is they all have positive karma's most of them have this and I think the karma
system is abused by this people.
