Wrong.
Mangadex allowed drama pages, but not comments about said pages since they were considered off topic, essecially the rules were censoring the people talking about said credit pages, but not the credit pages themselves, giving a platform for one side of the story only. Hence why the rule was changed after hours of discussing it.
There's other reasons for why chapters were pulled but let's not get into that. That's the main one.
Not because of the credit page itself, but because of the censorship when trying to respond to it.
