This is a tough one. While we all want to be aware of unsafe divers, there isn’t an easy (or legal) way to report situations like this. If you posted a comment on the offending members profile, they could easily delete it. If you posted their name and explained the situation in a forum topic, they could sue you for defamation of character.
I’ll leave this up to other members to comment and suggest ways to handle these types of situations. As the owner of DiveBuddy, I need to remain partial to everyone and simply provide a fun, easy-to-use social network for divers.
I will also remind you of the Report link on member profiles and all other content on DiveBuddy. When reports are provided from multiple members, the offending member or content is automatically removed from our site.
