The TechCrunch article in 2009 criticised the website for being creepy http://techcrunch.com/2009/06/19/twicsy-is-a-killer-and-kind...
"As you might imagine, this service pulls up a lot of slightly personal pics, such as couples being all cutesy together. Since you don’t know any of them, it’s slightly creepy. But hey, if they don’t want those seen, they shouldn’t be sharing them over Twitter in the first place."
