I have an self appointed organizer at my local store that is harassing other DMs that want to run AL content. This person has berated myself and another DM at the store for wanting to run AL content that we prefer. They even went on to post that I was refusing to cooperate with them. I've been playing in this DM's game for around three months and have enjoyed the games. Our groups started getting larger, so large that we had to start turning away players. So, I offered to run a second table instead of playing myself to handle the overflow.
When I advertised the game as rotating weekly from AL Content to Non-AL personal content, they started sending me messages and posted I was refusing to work with them and should not be allowed to post my event on the store or Adventurers League site. Then they started berating me in text messages on our private Discord server. They have argued with another DM that was running AL-compatible content on Saturdays that did not have any support from the store.
I'm not sure if this person is an "official" AL organiser, or if they just say they are, or how I would go about checking. They have no affiliation with the store at all; the store knows nothing about AL, and does not officially have any role in running or organising it.
Do I even have to deal with this person, or am I allowed to run my AL-legal games apart from them completely? I just want to run my game and have a good time; I don't want to deal with this person.
Am I required to work with an organizer that is bullying other DMs and being rude and harassing in texts and posting such nonsense on my event listings, just so that I may run AL-legal Content at the same store? Do they have any authority to control what games I can run there or what I do?
