There are some games that just tag vn, because they use renpy or because they have dialogue. I even have seen games that tagged point&click, because, you pointed and clicked, but those were not the type of games that are called point&click.
Not really efficient to try and exclude each game individually when they just keep coming consistently.
My point is, there are not that many adult games, once you select a tag or two. Selecting those individually is not that much effort. Also, if you browse by popular sorting.
Btw, if you want to, you can use my script to exclude multiple tags, but it takes a few minutes to set up. About a minute or so for 1000 games.
1. You configure the style {display:none} to be on button 1 (should be default).
2. Search for whatever tag combination you do not want to see.
3. Have endless scroll active and scroll down
4. Go to top of page.
5. Hover over the first game.
6. Press and hold 1
7. Do not get dizzy, while the games dissappear.
8. Repeat after a few months or add new games as needed.
It's easy to select more than you wished for and a hassle to remove it from the list (you need to switch style and press 1 again on the games you accidentally added). You can also export and import lists and there are two lists and two styles to switch between for each list.
If you try this, you could also use the genre filter tampermonkey script I made. It can filter 1 genre. The main genre. If a game did not set visual novel as the main genre, it will not work.
But my recommendation is, to select individual games. It is more effecitve than you might assume, unless you browse the recent page. And if you do browse recent, that method above will obviously not work.
For your case, using the genre filter and individually selecting games should be most effective. You could also add the regular exclusion of 1 tag to that.
