@Travelsignposts     3 January, 2021
    Twitter Travelsignposts Tony Page from Travelsignposts Pty. Ltd.:
Pritam replied promptly to my query and drew my attention to an egregious (and longstanding!) omission to delete a vulnerable file that his script had picked up. I felt like banging my head against the nearest wall for missing it...so he saved me a fractured skull!
I see that Pritam has found literally hundreds if not thousands of vulnerabilities across the web, and provides a great service; his programming skills speak for themselves, as do his high ethical standards.
Thank you, sir!
