I get why they posted it here (and they are the mod here) but yeah it is a bit of a weak fit. This likely fits better in !weirdgirlmemes or !2meirl4meirl or something else like that.
I'd say it's alright as filler content but it might make sense to raise the bar depending on the rate activity.
Also it might be better if it was just the second panel and had more refined visuals. Not sure if anything else supports it, but on Kbin you can microblog on any community so that could be used for content that fits less.
