Warning: The filter lists contain profanity that may not be suitable for younger readers. Unless you are comfortable with this, you should not click any of the Expand buttons.
Roblox has a chat filter that prohibits players from seeing profanity and restricts personally identifiable information, which replaces the now-discontinued Safe Chat that was previously used to prevent young players from sending messages that were not pre-programmed. The text filter is provided by the CommunitySift service. Since CommunitySift uses multiple rules and text classification techniques to filter phrases, the lists in this article are not representative of the entire range of words that are filtered.

Madness is ending

So many users got angry at Roblox for blocking LGBT terms, however, they are out of the filter now. This means that "gay", "lesbian", "homosexual", "transgender" e.g. are no longer blocked. However, if a person tries to insult a person saying "you're gay", it will be censored out by the moderation system.

List of filtered words

The chat uses a predefined list of words to filter, and messages that match one of the words in this list will not be broadcasted to other players at all. Most words are explicit language, so if you are not comfortable with this then it is not recommended to expand either of the two lists.

This is the word blacklist used by Roblox, extracted from diogenes.fnt:

A different filter is used for messages in games and on the website, when they are not in in-game chat, which replaces letters of words that are filtered by the pound (#) sign instead of blocking the messages completely. This filter list is not public.

Phrases that are getting censored

A glitch (still not patched yet) is causing innocent phrases to get blocked for no reason. The following phrases are:

  • met at school
  • doing man
  • (any number) well
  • did dude
  • I am too (fixed now)
  • one two three four five
  • bowser logan
  • Jake Paul [the funny theory]
  • that's gay but not "that is gay"
  • numbers [1, 2, 3 e.g] (if said more than 5 times)
  • does your (family member) 

Criticism

Chat filter

Users are bothered by the fact they cannot say simple sentence words such as "the" "my" and other words such as "town" and "headphone", and numbers, causing support groups to rise and users complaining about it on the Roblox forums. A new chat filter "update" also means that the filtering system for accounts under 13 and in certain games for above 13 (13+) users have become aggressive, blocking any numbers for those under 13 and simple words. This also made the community very upset. Some people have also complained that they can't even say 'Roblox' on certain games.

Other

People complain that other words or people's names such as Discord, Frederick Douglass, tran, and sometimes well were getting censored no matter what age the player is (It is probably just for safety, so the user doesn't get lured to a discord server and encounter other dangers like Online Dating, Scamming, etc.). The words "butt" and "naked" are also censored. This is probably due to online daters referencing inappropriate business in the community. Some players also say that butt should not be censored if damn is not. While this may be true, damn is not really 'terrible' profanity, as it's based on milder ways of speaking the terrible mouth. 13+ users sometimes complain on how limited they are on things they can say.

Funny Theory

It is now visible that Jake Paul is now filtered but Logan Paul is not. Some people think Roblox is a Logan Pauler, and told CommunitySift (the company to make the filter) to block Jake Paul. If a player tries to say "I like Jake Paul", it will be filtered out by the moderation. It is not confirmed this is true, but 75% of the players think this is the case. This was first found out by a user in the game Fencing by Stickmasterluke on August 30.

Glitches

Section contains profanity not suitable for younger readers.





2017

In early 2017 (around February; March), some users were able to say the words "ass" and "nigga", getting passed the filter towards everyone else.

In mid 2017, the chat filter was claimed to be completely messed up. It acted a lot like the 2013-2016 filter, until it was updated. This made everyone able to say lots of things like ass or piss. There was a time that at rare occasions you could even say "shit", but this has been patched during this time. "Fuck" got passed the filter if a player was to add a symbol at the start or ending of it. This was later patched, just like shit was. However, players could easily say shiit or shjt to get around this. Players could say fuu.ck or fu.ck to bypass the F word. Players say this glitch was caused by Roblox whitelisting usernames, which were the words used here. These usernames are now terminated, patching the glitch.

2018

In 2018, people have found a way to say "Fuck" in the form of f34k, fu etc.

Other

In late 2017 - early 2018, there was a glitch that allowed players to say "dick" if they said anything with "ken" or "ngen" in it. Examples (warning profanity): "longen my dick daddy", "I wanna thunderstriken my big fat dick". For some users, you could actually just say dick without anything in it, but this was very rare. "Big fat dick" was not censored for a while as well. Starting April 2018, some players were able to say more words that others couldn't say. These words are "cum", "rape", "hitler", "retard", "cok", "kkk", and "queer". This glitch has been patched in mid-June 2018.

Some phrases are able to get passed the filter. Some like "earth porn", "moby dick", "suck a dick, clark", "hey sexy/hi sexy", "EATShit", "it's fucking good", "rape/cum me/my daddy/dad/mom/mommy", "gay", and "fuck isis" show a good example. Surprisingly, these actually worked for <13 users.

Ever since the new 2017 filter, everyone's filter is very buggy and sometimes appears as if a word that is only 4 letters long could turn into 17 hashtags. It might be a glitch, or it was intentional in order to prevent the other users from recognising the words. This (maybe) glitch has not been patched yet.
