Are you saying a third party program should be required to complete this game? If so, what's the difference between that and mods? You are using outside tools to better coordinate. Sounds like you are one step from saying mods should be required to play content. You can do whatever you want in your static content. You can invite and remove anyone you want from your private parties. This is public content, you get no say. Sorry but that was what Square has intended, if you do not like it, yell at Square or don't do it. Violating terms of service by harassing other players and refusing to rez them is not okay. If you did that in roulettes you would be reported. This content is public content just like roulettes. Follow the rules.
