As an update, a workaround I've come up with is to use Plugin Organizer. My problem was that Fotomoto wasn't blocked on The Event Calendar pages because it doesn't recognize them as actual categories or pages. Plugin Organizer, on the other hand, does recognize them and allowed me to disable them.
However, I'm not going mark this as resolved because I feel like it's a problem other people might have that won't be easily solvable. Trying to buy squares of Google Maps through Fotomoto is somewhat useless and I think that it is a bug that needs to be resolved.
