An admin is not allowed to block people for no given reason. Your unfair block on the Deadpooltvwiki X-Men movies wikia just because I asked a question is a violation - you broke the rules. You have been reported to fandom while they review it - you might end up being banned permanently on every single wikia.
Because the infobox pictures are supposed to be the ones from promotional material, not from screenshots from the films!
When a new X-Men movie comes out with new promotional body shots, then you can update them. Or if there are any characters who don't have photos in their infoboxes, and have been portrayed in the movies, then you can add them!
