Something with adult work you need to be more careful with using language for example
Girls username used to say deep throat they now say "DT" It could be something to do with the age verification over 18 ,
In the OP's case was probably just a bot who flagged the word daughter (there'll be loads ) child, children, son, maybe even niece and nephew , junior . Just anything I guess that indicates a family member or child activates "bot moderator"
