In western europe, this is a communist symbol more than anything, to make people remember that they were the one resisting and were also dying in concentration camps. Some communists anfa groups are indeed using it, but as a small badge. the first link is referencing this, the second is not triangle but red/black flags, the third one is laughable, don't know about the fourth one and the last one is the anarchist flag.
