Lol, report writing is so important. Every time I sit down and write a thorough, step-by-step report, it flies through triage and normally gets accepted at the correct severity. Here are some tips (that I still struggle to implement) from years of bug bounty report writing:
Embracing the World Organisation is working to provide humanitarian services to all the refugees across the Polish border at Budomierz. #RussiaUkraineCrisis @tapasjournalist
Warner Bros. Television mourns the tragic loss of our dear friend Bob Saget. Bob was a father figure to many worldwide in his role as Danny Tanner on Full House. Our thoughts are with his family, friends, colleagues and fans.
I wonder how people can draw so beautifully, that the art can mesmerize anyone! Credits to my friend @Ashwathi_sasi, a true magician in disguise. (PS: orignal quote by Kano Jigoro)
