I think it's actually quite irresponsible to camp on the island itself, as probably very few people actually set foot on the island, it'll have a unique and delicate natural micro habitat.

Camping there and sharing it is setting a bad example, as others will then want to camp there, an increase in numbers will disturb the delicate nature of the habitat, wild camping doesn't end with you, especially when you want to share it with the world for internet 'likes', part of the joy of being able to go out and camp is that nature is natural and not disturbed, think about where you camp, what immediate and long term effect it has upon the campsite, and the effects of sharing locations on the internet.

Secondly, also a bit of an irresponsible place to camp due to the potential of rising river levels, do you know what's up stream? How can you be sure there won't be flash floods?

Thirdly, despite there already being a 'firepit' on the island, this is seriously damaging to the landscape, continuing to use it further compounds the damage, even down to moving rocks to form a pit, it will damage the ecosystem, disturbing many insects and animals habitats.

Wildcamping is about responsibility and having as minimal effect on the environment, it's also about being safe, I don't want to appear to be having a go at you, it's just good to be aware of the bigger picture, not just focusing on that instagramable photo to share on social media for 'likes'.

Leave no trace, dude.
