And let me tell you that in Chaos Data center BA discord, players are adviced to ignore the griefers, "snipers", and anything alike which is to say this is for their own good in case the arguments and griefings turn into report wars.

Can I ask why would you want to have a party with griefers to begin with? This is not all about BA since the core mechanic of this game happens to be MMO where player needs to be cooperative to other players in order to clear contents. The idea of "sniping portals" is not any difference than any other occurences happening in any other contents this game offering when players are unwilling to be cooperative because they have their own way to play the game that's against of what the community as a whole prefers.
