I forgot to upload before I post and ended up editing the note to add the pic but it doesn't seem to be visible for you... So here it is again...

I think they set the content warning I. It as a joke for the food being too sexy. That's how I read the joke anyway.
But yeah, you can do that on some apps, amethyst, coracle. Probably loads more.
Ok that's funny! I am known to be slow with certain types of humour 😅
Lol. It's also possible it was a mistake. I've accidentally pressed the bottome bar options on amethyst before ¯\_(ツ)_/¯
Ah yeah.... Ok... I see where it is... 👇🏻 
That's it, for warning the note. For a single picture you have to check it before uploading
It's fine i'm slow sometimes too 😅 but yes that's me who set the explicit warning. I'm using Amethyst, i can set it only for a picture or for a complete note.
Now I am laughing... 😂
Exactly! For the #foodporn
