Identity – Have the credentials of politicians been forced?

D & # 39; here:

It should be noted that a few years ago, a group of far-right politicians in Sweden were exposed to the dissemination of racist and anti-Semitic waste on the Internet, thanks to the strength of their gravitars.

Have political identifiers (which are not limited to Sweden) been forced?

If you find a source for the incident related, I will also appreciate it.
