A way to show off Filler Episodes you havent watched

What is considered a filler episode and what isn't lay entirely within a matter of user opinion. There is nothing, no function whatsoever the site can have to mark individual episodes in this way. If you want to leave a comment on the episode you can do that.

There is one issue though- if you are not watching all the anime, you should not be marking it Complete.
Complete means you watched the entire thing, from the first minute to the last, no matter what the content of the episodes.

I think that's being too prescriptive.

If someone watched a show but skipped an arc they should be able to indicate that they're done with the show by putting it in completed and shouldn't feel any sort of "social pressure" to go back and watch the episodes they didn't want to watch.

For example you can currently edit a show in your Completed section and change the episode count to something less than the total. The guy could do that for Naruto Shippenden, but then put in the tags a mention "skipped fillers". Nobody should get upset about that, it's their list after all, and they're being factual about how many total episodes they saw, and the fact that THEY consider themselves done with the show - which is ultimately what putting something in "Completed" means - I AM DONE with the show. It doesn't matter if other people disagree, because it's me watching, and the shows I'm finished with go in "Completed", they don't clutter up "Watching", "On Hold", "Dropped" or "Plan to Watch" because they don't belong there.

Nobody should be able to complain "yeah but they didn't 'really' Complete it". Because, who cares? It's their list and by editing the total seen and leaving a note about skipping the fillers they're being more honest about what parts they saw. We're not their parents telling them to eat all their peas before leaving the dinner table, their list is ultimately for them and they can say whatever they want in it.

@cipheron You are literally making an argument that it's okay to lie and misrepresent. LOL seriously
Just because you can get away with something does not make it right.
