And a question: Are there any genres nobody here likes, meaning I should refrain from posting these?
I don't think anyone here likes adventure games, so you should avoid those.

In all seriousness though, I doubt there's any genres that everybody here dislikes, so just keep posting any free games you find.

Also,
Ziggurat is currently free on GOG.com. Just go to the homepage and you should find it on the banner at the top.
