A computer-readable storage medium storing a program, which, when executed by a processor performs an operation for evaluating a chat message, the operation comprising:

• associating each word in the chat message with metadata, wherein the metadata identifies a word type and usage for each word in the chat message;
• identifying one or more safety rules associated with the metadata, wherein each safety rule identifies an ordered sequence of one or more sets of words;
• applying the safety rule to the chat message to determine whether a sequence of words in the chat message present in the ordered sequence of sets of words;
• and
• upon determining a word, from each set of words in the ordered sequence of sets of words, matches a corresponding word in the chat message, blocking the chat message from being sent to a message recipient

A system, comprising:

• a processor;
• and
• a memory, wherein the memory includes an application program configured to perform an operation for evaluating a chat message sent between users of an online environment, comprising:
• associating each word in the chat message with metadata, wherein the metadata identifies a word type and usage for each word in the chat message,
• identifying one or more safety rules associated with the metadata, wherein each safety rule identifies an ordered sequence of one or more sets of words,
• applying the safety rule to the chat message to determine whether a sequence of words in the chat message present in the ordered sequence of sets of words, and
• upon determining a word, from each set of words in the ordered sequence of sets of words, matches a corresponding word in the chat message, blocking the chat message from being sent to a message recipient
