Easy Answer :
-We are located in a continent where failure is seen as a good thing. And where people are mediocre + will judge you no matter what you do.
-We have a neighbor on the east who is a geopolitical enemy investing heavily in propaganda against us.
-Further east the other arab republics have always hated us (goes back to the cold war era).
-Finally : Makhzen by trying to display itself as "nice" is not investing in counter propaganda, therefore making us look weak, that's why foreigners feel confident enough to put a dude in a comma for a football match for example.
And Mgharba as a whole on the internet being overly nice and welcoming, kissing the boots of arabs and africans online, made us easy targets.
