I have never had a FB account and I don't really ever visit it as a guest, lurker or whatever.
I'm on FB a good bit because my wife likes to post pictures of us.
I am rather shocked that your entry or comments on FB would result in your receipt of advertising relating to moderation.
It sounds like something which would come from the spirits industry.
This forum and a few for other interests of mine (e.g. music blogs) are the closest I come to being on social media.
I put no stock in moderation for someone who is a true alcoholic based on what I have witnessed over the years (primarily funerals).
