I had the same problem with them OP, its not official discord so complaining here won't get it fixed.
I'm a former owner of Arma-Life (The new one made in October 2018) after starting the project for Silverlake Repentz and Travis came over and started working on a new framework which we used to great success but that also brought in the PsySyn fan boys and the man himself which got us target by BI (We got a claim on our server days after launching for quote "Having a GTA4 Bridge" that they ASSUMED we had to rights to. But in the end it is BIs service and game so they had the right to do that.
How i personally got banned from the Discord was that i went in there to calm the fire that was started from one of the guys at TFAR saying we had to rights to use and was going to DMCA us (He literally did nothing except some tiny snips of code and edits) so i had to defend what was essentially my creation that piggy backed off the fame of the OG Arma-Life.
Proof i'm not just spewing shit
Needless to say i cut ties with ArmA-Life after my project was thrown off the rails by the community i was running it under (i needed funding and connections to make it successful). To those of you OG (My OG) ArmA-Life readers that see this and remember MY ArmA-Life i never meant for it to turn into TDM.
TL;DR, The sweaty ban happy nerds in the discord aren't worth messing with. Stick to official BI communication routes.
