I am glad that you are taking the time to police your network. However also for future reference, I only use my own images and always have which means, they are my photographs. One of the issues that the tribes are going to face is trying to make claims on generic labels like "photography" "investing" or "technology". It would be different if the tag I had used was a frontend specific tag like "creativecoin" Generic tags are generic tags.

For marketing purposes the generic tags work well at this point because each tribe can pull in a lot more content to fill the feeds, but in the future each will need market differentiation and the generic tags are not suitable for this purpose. What I am hoping is that the tribes will offer unique experiences and specific tags for purposes that empower their users as there is a lot of benefits and potential in positioning within the marketplace. :)
