I only posted two days ago about checking your sources. I bet these people wished they did now after a week of retweet (RT) based goofs, where one tweeter would ask a celebrity to RT their picture of a certain "family member" - but instead of including a real image of said family member, they decide to use various "other" images.
As you can see below, a load have fooled them and they've gone on to retweet them - however after various replies like "he's britains most notorious paedophile", etc.. the said retweets were un-retweeted. Here's a few that have happened this week:
Billy Ray Cyrus (country singer) fell for a Jimmy Savile tweet
Oliver Heldens (music producer) fell for a Raoul Moat tweet
Donald Trump ('murican) fell for a Fred West and Rose West tweet
MC Hammer (rapper) fell for a Peter Sutcliffe (aka The Yorkshire Ripper) tweet
It wouldn't surprise me if there's a few more from this week, if I find anymore I'll be sure to add them to the list.
