Under Serial Update there is a story called A Sharing Pact by Mark Gander. I know nothing about the story or the author. However, it is an excellent example of overwhelming a reader with story codes. There are 9 lines of story codes. I'm not going to count the codes, but it looks like over 100 codes.
As a reader, I take a more complex view of long code lists.
1. The longer the story is the more codes in can support.
2. Stroke stories should be relatively short. Novel or Saga length stroke stories are absurd.
3. I am somewhat forgiving of lots of codes for a short story if it's in progress and there is at least the promise of being long enough for the code list.
4. The tags fall into groupings. A number of groupings have generic tags with more detailed tags. If you code for all the detailed tags, just the generic tag would work better.
5. There is one group of level/type consent tags. Not all consent levels/types mix well in a single story.
6. There are three groupings of of genre tags. Not all genres will mix well in a single story and having too many genres makes a mess.
7. Age/gender combo tags. I am a bit of a fan of harem/polyamory stories, but I prefer stable groupings to swinging. Less is better unless your story follows multiple groupings.
Now let me review the tag list for A Sharing Pact against those criteria.
1. It's at 27 chapters an 481K it's a fairly long story, but the tag list demands a saga on the order of the Lord of the Rings Trilogy.
2 Long story, but it's coded much sex not stroke.
3. In progress, but it's been 7 years and it's still only 27 chapters and 481K. I don't think it will ever get long enough to do justice to that code list without being a stroke story.
4 Groupings with generic/detailed.
4.1 Incest, Brother, Sister, Father, Daughter, Cousins, Uncle, Niece, Aunt, Nephew, InLaws
Why not just incest?
4.2 BDSM, DomSub, MaleDom, FemaleDom, Spanking, Rough, Light Bond, Humiliation, Sadistic, Torture
The only detailed tag left out was snuff. Personally I would have dropped everything but the generic BDSM, Sadistic, and Torture. The latter two because they are major squicks even for some people who otherwise enjoy BDSM stories.
4.3 Interracial, White Couple, Black Couple, Black Female, Black Male, White Male, White Female, Oriental Male, Oriental Female, Hispanic Male, Hispanic Female, Indian Male, Indian Female
Got the whole group in this time.
5. Consent tags: Consensual, Romantic, NonConsensual, Reluctant, Rape, Coercion, Blackmail, Mind Control, Hypnosis, Drunk/Drugged, Magic
Okay, he threw in everything except pedophilia, Lolita, and slavery. Why slavery was left out I have no idea.
I do think you can have good stories that mix consensual and non-consensual elements. However, Romantic generally doesn't mix well with the more extreme forms of non-consent.
He probably could get away with just consensual and non-consensual.
6. Genres: Humor, Science Fiction, Post Apocalypse, Extra Sensory Perception, Paranormal, Ghost
Too many for anything short of an epic saga. Probably too many for an epic saga.
Science Fiction and Paranormal are hard to do well together, so are Humor and Post Apocalypse.
If you are going to mix those, the description better sell it, and the description on this story caries no indication of SciFi, Paranormal, or Post Apocalypse.
7. Age / Gender: Again, the author threw on just about everything, but the description doesn't really fit teenagers or any of the teen/teen or adult/teen combos.
You get down to sexual activities, fetishes and again, the author threw on just about everything.
My opinion, the author tagged out the story with no real plan for where it was going.
