First off, porn comics are not suitable for general consumption. They can corrupt the mind and lead to unhealthy thoughts. Also, it's illegal in many places to distribute such content. So, we definitely shouldn't feed it to humans.
The differences between 'a' and 'x' porn comics can be quite diverse. It could be the way the characters are portrayed, the quality of the illustrations, or the themes explored. Sometimes, one might have a more unique approach to sexual content than the other.
The answer is not straightforward. The feed could be fiction if it's created for entertainment or imaginative purposes. However, if it aims to inform or report on actual happenings, it's not fiction.
The main difference might be in the characters or scenarios presented. 'A vs X' comic porn could have specific character conflicts or unique storylines that set it apart from the usual.
To stop stories on the feed, first check the app's settings. Sometimes there's a specific option for controlling stories. It might be under 'Feed Preferences' or something similar. Also, make sure you update the app to the latest version as new settings could be available.
