off of 作为复合介词为非正式用法，在正式口语或写作中应该避免。在表示来源这个意思时，off作为介词也是非正式的。较为正式的用词为from.

你的句子中，profit off of sth/sb = profit off sth/sb = profit from sth/sb.

The Free Dictionar关于off of的用法说明：

Usage Note: The compound preposition off of is generally regarded as informal and is best avoided in formal speech and writing: He stepped off (not off of) the platform. Off is informal as well when used to indicate a source. Formal style requires I borrowed it from (not off) my brother.
