Do you advocate polyadvocy?
I have genuinely no idea what that means. It returns zero Google results.
If you mean "polyamory advocacy" in the sense of fighting for laws and other policy changes regarding healthcare, finances, insurance, child custody, adoption, hospital visitation, employment, etc. that serve the needs of polyamorous people and families, absolutely.
If you mean evangelizing polyamory as a relationship style that everyone should adopt, or trying to convince or cajole people into polyamory, absolutely not. There's a time and a place for "hey, there's this thing, it might resonate with you, here's some info about it!" - people deserve access to information that might help them understand themselves and be intentional and healthy about their relationships - but that's where it should end.
If you mean something else, then I can't answer your question, because I don't understand it.
