Chat/Filtering

Roblox has a text 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.

In games, text filtering is done with two functions of the service. FilterStringAsync is used to filter messages sent by one player and intended for a single other player, while FilterStringForBroadcast is used to filter messages broadcasted to all players. To be compliant with the filtering rules, game developers must filter all messages which are shown to players in GUI objects, character names, etc. If the place's creator failed to comply with this rule, their game would be put Under Review. List of Filtered Words contains words that may offend you, see at your own risk.

Criticism
Users are bothered by the fact they cannot say simple sentence words such as "the" and "my", and numbers, causing support groups to rise and users complaining about it on the ROBLOX forums.

This has now lead to Roblox revamping their filtering system. The parents of accounts under 13 can now only allow communications with people on the player's friend list or restrict chatting altogether. This also means that the filtering system for accounts under 13 and above 13 (13+) have become aggressive, blocking any numbers for those under 13 and simple words. As stated before, this also made the community very upset. Some people have also complained that they can't even say 'Roblox', though this is not confirmed.

List of filtered words
The chat uses a predefined list of words to filter. Messages that match one of the words in this list will not be broadcasted to other players at all. 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.
