Seems to be working better than expected, since they've somehow tricked you into sharing this ad with all your followers. :/ See: https://www.popularmechanics.com/technology/robots/a19445627/the-hilarious-and-terrifying-ways-algorithms-have-outsmarted-their-creators/ … and similar.

Out of curiosity, if you go to Google's ad settings, what is your gender listed as? Anything else listed that could trigger this ad? https://adssettings.google.com/
