If anyone's wondering why a lot of ICO whitepapers seem to be plagiarized (I've seen a lot of scam accusations to that effect), it's because of stuff like this guy is doing.
people here are exposed and vulnerable. I am not liking this silent killing, personally i had no warning and i assumed common sense would play its role to each and anyone's benefit.
You're not a victim here, so there's no need to play that role. Reading forum rules is your warning, and I don't know about common sense, but it's an ethical issue that comes into play when you claim someone else's work as your own. It isn't right to do so, and there's a rule against it here.
I hate to bring this up again, but the PM that the banned user gets really ought to contain at least one example of the plagiarism offense so they don't waste people's time playing ignorant and/or demanding proof. I get that there would likely be threads begging for mercy, but at least there would be no reason for the banned member to ask why he got banned. Theymos, if you're out there please heed my cry. It really isn't a bad idea IMO. Whether it could be implemented simply and in such a way that it's convenient for mods is outside my realm of expertise, but I think it should be done.
