When someone makes a Doujinshi, often it is based on an existing manga/other.
But even more often it is "deformed"/degraded into something different.

I would love to see the option: "Parody" for Series Relation in User CP.

Downside: Nothing.
Upside: Win:Win

Thank you all, for the incoming discussion waves 🤣

I don't think we will be doing that, because the "parody" category already works very well for that purpose. Since categories are part of the advanced search feature, you can easily search just for doujinshi that have been tagged as parodies.
