There are probably some people at your club who you'd prefer not to play with. If so, you can set Pianola to block these people from seeing your adverts.
Click on Partner finder and then Preferences.
By default, all other players will be able to see any adverts you post in the partner finder. To prevent this, click on the 'block' option for each player you would prefer not to play with.
They will not know they are blocked, but when they visit the partner finder they will simply not see any of your adverts. Pianola will not send them any emails about you, even if they subscribe to be notified of your ads.
