Kokhloma is a traditional Russian decorative style painted usually on wood. It has the misfortune of being phonetically similar to the word “Khokol” (a pre-modern ethnic designation meaning “Ukrainian”, now considered derogatory).
Khokhloma makes Facebook algorithms go crazy. A man posting a picture of a rocket decorated in Khokhloma style was Zucced for his post.
Another reason why you should avoid using Facebook for communication. It does not understand the nuances of language and culture.
