Some of those users really deserved the ban as they copy-pasted content to get merit, to increase their post count in signature campaigns and most were aware of what they were doing. However some users did it while participating in bounty campaigns and ICOs wherein they followed rules that required them to do so and even though it is wrong, I feel such participants should be given some warning and signature bans instead of being permanently banned. In such cases the managers and project managers should be banned just like it happened earlier when the rule of many bounty campaigns was to post in the ANN thread.

Sometimes users mistakenly post email content on the forum without a source link so I don't know if that can be termed as plagiarism as in such cases citing the source is tough.
