I make a lot of Google searches for places in the Sex Listings, either to check the address, the hours, or the maps' geo-coordinates or to check when someone says a place is closed.
I submit corrections occasionally to Google Maps for places in the Sex Listings, whether they are gyms, bathhouses, adult video stores, or whatever.
I guess at this point I really don't care what Google's computers and algorithms think of me.
I don't see it affecting the ads I see
except when I'm doing these searches. In that case, it seems to be contextual based on my search terms, not so much on my search history.
