RTL Nieuws managed to break into the social media accounts of various politicians by using previously leaked passwords. With some of them, including the Twitter account of SGP leader Kees van der Staaij, the journalists left a message to show that they were there.
"This account has been leaked and is therefore vulnerable to hackers. Signed Daniel Verlaan and Siebe Sietsma of RTL Nieuws", a tweet read on Van der Staaij's account. The tweet has since been removed. They also broke into CDA Pieter Omtzigt's LinedIn account and various other unnamed politicians' Facebook accounts.
