Straight from the SWGoH ToS
Interfere with or disrupt another player's use of an EA Service. This includes disrupting the normal flow of game play, chat or dialogue within an EA Service by, for example, using vulgar or harassing language, being abusive, excessive shouting (all caps), spamming, flooding or hitting the return key repeatedly.
Harass, threaten, bully, embarrass, spam or do anything else to another player that is unwanted, such as repeatedly sending unwanted messages or making personal attacks or statements about race, sexual orientation, religion, heritage, etc. Hate speech is not tolerated.
Contribute UGC or organize or participate in any activity, group or guild that is inappropriate, abusive, harassing, profane, threatening, hateful, offensive, vulgar, obscene, sexually explicit, defamatory, infringing, invades another's privacy, or is otherwise reasonably objectionable.
Engage or assist in cheating or other anticompetitive behavior (such as boosting, collusion, and match or matchmaking manipulation).
Promote, encourage or take part in any prohibited activity described above.
With these direct quotes, I would enjoy an explanation of how shard mafias are NOT a violation of the ToS. It outright says boosting or cooperation, any anticompetitive behavior, is a violation.
I get it works better for everyone, but how is it not a violation of the language there?
Edit: Thanks to whichever mod corrected the title and location.
