Well, maybe both cases are not the most obvious plagiarism, because some words have been changed. But the fact is that both posts are completely useless and I see them as spam.

Mimi already has a "Watched" badge, which means that the moderators have noticed it. Considering that she is a new member, maybe she is still getting used to the forum, so I would give her another chance. Maybe she should be directed to this topic so that she can see her mistakes and still have time to fix them.
Awtzu203 copied the text from the Unijoin site in their ANN thread and it is very difficult to explain what he wanted to achieve with it. Since he is not in a campaign, the number of posts is not decisive for him, unless he wants to reach a forum rank acceptable in campaigns as soon as possible.
@Don Pedro Dinero, To be sure if something is plagiarism, use free tools like for example duplichecker.com or plagiarismdetector.net.
I will send them a PM with a link to this topic, maybe they can give some explanation in their defence. Or at least to recognize their mistakes.
