Korean swear words, answered

What is this list for?

Building or tuning a filter, moderating a community, or understanding a message someone sent you. It is 70 of the 167 words in the Korean lexicon Unprofane reads, picked for the words people meet: everyday swearing and insults first, then words for the body, then slurs.

Why are some words masked?

So the page can be read anywhere. Mild and moderate words are printed in full, strong words masked in the middle, and slurs and the most extreme words shown to their first letter with what they mean; the download has every one in full. There are no threats, no words that urge self-harm and no words for sexual acts. Strength is the lexicon's grade, and each policy treats each grade in its own way.

Can I check a spelling myself?

Yes. Each spelling on a card is one the engine reads back as its word, and Try it opens it in the playground with the rules alone, so it reaches no model and is not kept.

Is a list of swear words enough for a filter?

No. A list matches words as they are typed, so every spelling needs its own entry: 960 for idiot alone, with common digits, look-alike letters and dots, before a single letter is stretched. A list that matches inside words to catch more blocks innocent ones: *ass* blocks 121 of the 20,000 commonest English words, pass, class, glass among them. The banned words generator counts both for any word; Unprofane reads every spelling in one call instead.

Can I use this list in my own filter?

Yes, under CC BY 4.0: credit Unprofane with a link to this page. The JSON and the CSV carry every word in full, each with its kind, its strength, its meaning in English and the other spellings the lexicon lists, built from lexicon 7fd3a314370b.
