If it is a copy / paste the thread you can report it, so that later the mod that takes the decision includes copy / paste or not.
Or even faster to handle you can post here:
Topic: Report plagiarism (copy/paste) here. Mods: please give temp or permban as neededIf it is a copy / paste later you can see the results, whether the user named @aishabinteali is prohibited or not
Oh, one more thing, don't forget to archive and provide the original and copied code, I mean the owner of the original thread and the copied thread.
