Should the be punished?
Disqualification from the campaign was their punishment. But, if you're talking about having them banned or tagged, for me, I guess that's too much.
should they be given a chance?
No. I gave everyone who participated in the campaign warnings on what would happen if they submitted a plagiarized photo a couple of days ago. Even sent an additional instructions on how to edit their wrong posts or delete the bad ones from the platform. But even with all that, those who got disqualified never listened. Is it as if they are thinking that they could get away with submitting a plagiarized photo and get paid without me noticing it. That right there to me was a clear intention of cheating on the campaign. So no. No second chances.
