Methods, systems, and products block objectionable content and substitute alternative content. Multiple fields of a preferred tag are retrieved from memory. Multiple fields of an alternative tag, associated with alternative content, are retrieved from the memory. A number of matching fields, between the multiple fields of the preferred tag and the multiple fields of the corresponding alternative tag, are determined. The number of matching fields is compared to a threshold value. When the number of matching fields exceeds the threshold value, then the alternative content is substituted for the objectionable content.
