I mean if posting of Japanese series actually stopped when posting of Korean series started, it's more likely that they're just the same posters posting about different things at different times i.e. probably posting fresh reactions when they read them. If they were different people, then Korean spam would have no effect on Japanese series discussion, since Japanese readers and Korean readers wouldn't be affected by each others' activity.
