Sometimes I can be helpful. Take the below, where I alert the Hare Krishnas here to an impostor in their midst. Or is he for real? Links in this post do not appear in the e-mail I've sent. Contact details taken from here.
Dear Mayesvara and Syamananda,
I'm writing to alert you to an impersonator in Dublin who is attempting to bring the good name of your organisation into disrepute.
He stopped me last Thursday on Henry Street and introduced himself as a travelling Yoga teacher asking for donations for Dublin's Hare Krishna temple.
He had no identification, and while his distinctive haircut suggested a monk I felt this was not enough to ensure authenticity. I recalled that your parent organisation had declared bankruptcy to avoid paying compensation to child sex abuse victims, and I asked him if he could explain this approach to me. This may have seemed a mite harsh but I was sure anyone authorised by your temple to collect money would have been appropriately briefed to discuss this matter with tact and compassion.
