Marveltvnews.com reports that Marvel might be censoring the criticism the
Ultimate Spider-Man cartoon has been getting lately. From the article:
"To make things worse, starting 2 days ago, Marvel and Man of action have been deleting most negative comments about the show. In fact i was surprised to find almost more than 70% of the comments that criticized the show have been removed, even though they contained no profanity. The other suspicious part are that new “positive” comments towards the show have been posted just today to stay at the top of the comments."
Whether this is true or not remains to be seen. You can read the rest of the article on the source.
