Hey,
I know some services that allow the users to switch the possibility on or off that Google and other search engines can find their profile when searching for their name. As someone that likes to have his online presence not easily findable via search engines, it would be great to have such a feature here too - since you have to register with your real name. I don't know if something like this is possible to implement here, and I also don't know how the other sites have done it, but I would really like this option. If people that do BJJ want to look up your rank (e.g. because you want to compete and they want to verify your rank), they can just use the Beltchecker Search, there should be no need for profiles to show up on Google, as that also automatically puts many if not all of the uploaded Beltchecker Images onto Google Images.
Kind regards
