Oh, them magats are violating a lot of laws, albeit mostly on a rather small scale. Most jurisdications are avoiding to persecute them since it's a lot of paperwork for a small effect.
For now. Because most of them might appear to be unfazed initially, but if the violations are repeated, the fines and punishments will also increase.
BTW...did you know that for example, India has laws which can bring fake news peddlers behind steel bars without having to resort to juristical gambits?

Seems like many countries including the USA are in dire need of similar laws.
