The feature reveals how people behind some of the most popular parodies — such as @MrsStephenFry — have gone on to earn commercial success, while others are altogether more sinister. The man behind @Lord_Credo managed to convince many that he was a personal adviser to British Prime Minister, David Cameron, and wormed his way into political circles. He allegedly conned some out of money, took advantage of the hospitality of others, and left the professional reputation of at least one “in tatters”. He even fabricated a malignant brain tumour, leaving one young member of the group “utterly distraught”."
