</center>

          Service Order

          

It is important that Profanity Filter node is used **after** the [Normalizer](/v1/docs/dataflow-nodes-normalizer) and [Punctuation](/v1/docs/dataflow-nodes-punctuation) nodes. Otherwise, the filtered asterisks will be seen as punctuation by the other services and be manipulated as such.

### Supported flow types
