That sounds like some kind of malware with your app... it's a direct link to the previous post in this same community. (they're all linked back and forward with direct links to the post.)
To be completely fair, the two links both go to other cute comics with nothing objectionable in them... but one of them shows two female characters hugging and talking about dating each other.
"Why are you posting links to porn?" looked indistinguishable from the American Far-Right talking point that any depiction of gay relationships is inherently pornographic.
