Methods and apparatus are provided for protecting users from objectionable text. Users are protected from objectionable text, by obtaining a predefined acceptable word list containing a plurality of acceptable words; receiving a textual entry from at least one user; and limiting the textual entry to only the acceptable words. The acceptable word list may comprise a dictionary of the acceptable words, and can be maintained by a central server or by a client associated with at least one of the users. The textual entry can be limited by only allowing the user to enter a subsequent character following entry of one or more entered characters if the subsequent character following the one or more entered characters comprises at least a portion of one of the acceptable words. The acceptable word list can optionally be updated with one or more additional acceptable words. The acceptable word list optionally comprises a context sensitive word list or one or more context sensitive rules.
