Figured it would be best to ask here instead of in the comment thread I was discussing it in here: https://e621.net/comment/show/3666571

Basically I'm looking for a way to blacklist all male/male, intersex/male, intersex/intersex and male solo content UNLESS there's female/female, female/male, female/intersex or female solo in the same image. So far I've been using "female" in all my searches, but then you get images like the one I commented above on where the female is in the background and not involved in the sex. I also don't want to simply blacklist male/male because then that blacklists images like lichfang's orgies, where you've got a ton of female/female, male/female and intersex/female with just one or two male/male or intersex/male.

I'm looking to do the following, but there doesn't seem to be a syntax to do it, such as the parenthesis I've put below:

male/male -male/female -female/female -intersex/female -(female solo)
male/intersex -male/female -female/female -intersex/female -(female solo)
(male solo) -male/female -female/female -intersex/female -(female solo) -rating:safe

I really don't think you can. There aren't tags to designate background characters. The most you can get is:
male -female
intersex -female
male_focus*
intersex_focus*

*These aren't tagged frequently. Because this seems to be important to you, maybe you could help out by tagging things that make it through your blacklist.

Also I didn't bother covering 'male/male', 'male/female' etc because just the gender tags on their own will cover that.

Found the man-hating feminazi! Just kidding XD

The best I could come up with is this:

rating:e rating:q male/male intersex/male intersex/intersex -female -female/female -intersex/female -male/female -ambiguous/female -lichfang

Putting brackets does not combine tags, so by doing "-(female solo)" all you've done is allowed "(female" but blocked "solo)", tags that obviously don't exist.

Unfortunately there is no way to blacklist images that contain, for example, male/male and a female in the background that's not in the action.

However, if you come across specific images you don't like, you can blacklist them. Scroll down and find the post ID in the Statistics section, go to your blacklist and type id:number on a separate line, so for example if you wanted to block my avatar, you would type id:1399650 into your blacklist on a separate line. All specific images that you want to blacklist must be put on separate lines.

You can also block entire user's uploads, so if you don't like a single thing I upload (you probably don't) you can add user:blacklicorice to your blacklist so everything I upload is automatically blacklisted.

Read more about the blacklist here.

This makes me wonder, since the blacklist is (or at least was once upon a time, not sure if it still is) processed on the web client, would it be reasonable to forbid [] from tags and use them for grouping tags in the blacklist? This would make certain kinds of blacklist operations a lot easier to represent.

I wouldn't mind a return of the boolean operators, either, but I understand how complex it is to implement complex parsing systems, and worse still to explain them to non-programmers. :P

Am I misunderstanding something? It looks like you're just trying to blacklist anything sex related that doesn't have female in it? It's either:
male -rating:s -female -solo
or as two lines:
male -rating:s -female
male -rating:s -solo

I'm not sure if the tags need to be separated out or not, you'll have to experiment yourself.

that would allow females only present in the background, and the first one would even allow male solo

Take a look at the lists he was going for:

Drift91 said:

male/male -male/female -female/female -intersex/female -(female solo)
male/intersex -male/female -female/female -intersex/female -(female solo)
(male solo) -male/female -female/female -intersex/female -(female solo) -rating:safe

All three of them include every possible female/partner position, and then at the end include a solo female. This would automatically include any background female.
I misread the last line, all he wants is male -rating:s -female and it covers all three lines.
