They even made a skin called Little Devil Teemo. Who actually finds "diablo" to be offensive but not the other 3? I discovered that it is blocked when I was trying to talk about the game, Diablo 3.
deathgod528 votesMaybe they dislike blizzard entertainment :)
AlienPrimate5 votesThis would only make sense if World of Warcraft, Overwatch, Starcraft, Hearthstone, and Heroes of the Storm were also blocked.
deathgod51 votesI genuinly don't know if they are. World of Warcraft and heroes of the storm seem to contain words that are used way to often to be banned.
TheMoralSupport1 votesOr hot sauce
A girl Supp Main10 votesDiablo can be used in a somewhat vulgar manner in Spanish. It's sorta like saying 'hell' if you drop it somewhere by itself.
Dextix LT8 votesSatan is actually blocked too.
Papa Andrei5 votesFun fact: Dio is also banned for some reason
Melledoneus3 votesD*OOOOOOOOOOOOOOO
Melledoneus4 votesEasy.
The first one is a reference to a demonic king of hell. The other 3 are alternative titles for Teemo.

LostFr0st2 votesThe last three are synonyms with 
; can't block champ names ofc.
AlienPrimate1 votesDiablo isn't even a synonym. It is the literal translation of devil in Spanish. On that note, do they censer their own skin name if you play in Spanish?
LostFr0st1 votesIt's likely censored since it's so close to the french version "diable" which is used for coarse language. In french church/religion related stuff is what they swear about.
And no, the skin name wouldn't be censored if playing in Spanish. I don't even know what they ended up calling it after localization to any spanish server (EU, EUW, and LAN?). It may not have "devil" in the title at all, they may have changed it to "demon" which would be more culturally acceptable. The NA server only supports english.

Zelorxon2 votesDiablo is owned by blizzard.
AlienPrimate4 votesThat has nothing to do with "diablo" being blocked in the chat filter.
TheMoralSupport4 votesPretty sure it's a joke, lol
koshkyra2 votesSatan is blocked.
Terozu2 votesLucifer means Angel of light. The other 2, Satan is blocked, they probably block specific names of evil gods. But Lucifer is still ok... appatently.
Leaf on Bush1 votesYou should have done a google search. There is no angel in "lucifer". It just means "light-bringing".
Lux = Light Ferre = to bear, to carry
Terozu1 votesBut it was the name of the Angel of Light, who later blasphemed against god and was banished from heaven, becoming Satan. And even with what you said, it'd be "Light Bearer" wouldn't it?
Leaf on Bush1 votesAnd still nothing about angel... the word existed before there were any christians. They just took the term and used it as name for their fiction.
Lucifer was the name that the romans used for the planet Venus, because it shines bright in the morning. Thats why it's also translated as "morningstar".

Because people back then didn't know better they often associated such celestial phenomenons with gods they thought its the god of the morningstar and the christians turned it into an angel.
Btw my chat filter is turned off so what am I even doing here. Idc lul
Terozu1 votesLucifer is actually just a translation from hebrew, the proper name, Hêlêl(again meaning light bearer, or more commonly Shining One)(It's pronounced Hey-Lel), existed long before Latin. About 300 years to be proper. Christianity didn't adopt it as an angel, since the idea existed before Rome's founding. The reason they use Lucifer is because Catholic was mostly just the old teachings translated to Latin. And Hêlêl in Latin is lucifer, but Hebrew (and the idea of the Angel) came first, it wasn't adopted from morning star, they only took the name, since it was the closest translation available. Similarly, God isn't actually God, the proper name is Jehovah, (Ya-hu-wah, not Je-hov-ah), or Yaweh(ya-way). The reason this name isn't in the present bibles is because it is tradition not to say his name for fear of desecration, though why it was actually removed is anyone's guess. And Jesus is also from Latin and goes back to Zeus if you trace origin. The proper name is pronounced Ya-shu-A. And is the hebrew equivalent of Joshua. In other words Jesus' real name was Joshua, and never Jesus, that started with Roman Catholicism. And Christ was Ma-shi-ac, or now, Messiah. Meaning the proper way of saying Jesus Christ, would be Yashua Ha Mashiac. Do not quote spellings, it's confusing.

The build isn't that idiotic though.

Rozzeta1 votesBecause Spanish is master language.
DeadUnborn1 votesIt might be used as an insult in spanish or italian speaking countries? not sure. Alternatively, it could be that it is muted from a previous Riot rule of censorship on religious matters that has since changed, but the filter wasn't updated
The Soulforged1 votesSatan is blocked by the chat filter I always get bleeped when I refer to teemo's true name.
