Where is MPL banned?

Could you please clarify for me which MPL you are referring to? As there are several abbreviations that could stand for "MPL", such as MetaProtocol Layer, Multi-Party Lottery, or even something specific to a particular country or region. Assuming you're asking about a cryptocurrency or financial product, could you provide some more context? That way, I can better understand your question and provide an accurate answer about where MPL is banned.
