Spark'd Upload: Unable to remove a household from the Gallery

do I need to flag all of my Sims4 Sparkdchallenge household & sims if it's still in gallery after my removal in Library?

People, upon years of searching, messaging Gurus, chatting with customer support, I have finally found a way by myself to remove this Spark'd plague from my gallery.

1. Go to https://www.ea.com/games/the-sims/the-sims-4/pc/gallery
2. Log in with your gallery account.
3. Search for your account by clicking on the "Browse" tab, selecting EA ID in the menu, and typing your EA ID.
4. Find the content in your gallery you want to be removed.
5. Press the flag icon, choose the "Harassment" category, and type anything.

After that, your item will be finally removed. 

For those who still have them when they login into their game, just remove them from favorites/delete them the regular way. 

You are welcome!
