My personal opinion -after having met many such characters- in India; either in Varanasi, Rishikesh, Vrindavan et al, as well as at the Kumbh Mela, is that the majority of them are fake in the sense that they're not dedicated ascetics, but individuals who are adopted a vagabondage lifestyle, begging for alms and food...under the guise of being holy and religious.
Lyn's last tip is to have your own website. "Show off your work on Instagram and Facebook, but do ensure you have a good, easy to use website too. It should have some of your best work (with lots of keywords!), any specialities, and awards/competitions you have won, and your contact details. It's too easy to get carried away, add thousands of images, and forget the basics. Keep it simple."
