Greg, How about just adjusting or changing the general policy of the site ? I am fairly new here and like most, dislike to be bombarded with all sorts of commercial things, however it might be a thought to review and accept profiles before they are posted, or have a particular more commercial section, where we can log in easily to gather info on travel, gear or whatever else that dive buddies wish to advertise Maybe you can make this a paying service, for a minimal fee ? in other words have ’regular dive buddies’ and ’commercial dive buddies’ that way we’ll know right away what to expect....
Good luck.
