The profile is there to give others who are trying to give you advice an idea of where you are in your diving. Your profile is there to help you in this way, not to impress anyone. Sure, anyone can make up a fake profile, but it doesn't help them get their questions answered more accurately.
I know it does say experienced diver with more than 10 years, but some people really have done only 50 dives in 10 years--you never know. You could put down in your profile a number of dives that you estimate you have done. You could put down what courses you have taken and what year. You could put down that you're a cold-water solo diver and the places where you have dived. There are spaces for all of that, I believe. It will help people focus their replies better.
