Namechanged and this is going to be long, so please bear with me and thank you for reading in advance. I need to get this off my chest and maybe someone will come along with good advice.
I joined an amateur drama group and after acting one season, my friend and I were given the opportunities to direct the next production which is a pretty big deal and we are very excited and happy. The group is incredibly supportive and everything is fine on that front.
However, there's one person who is making trouble. I will try not to dripfeed and give you as much backstory as possible.
This person had been a member of the group before my friend and I joined but left the season we joined after a massive rift, caused by him being unreliable to work with, always late and quite volatile at times (not physically, but verbally abusive). It got so bad that the manager of the group blacklisted him, so he wouldn't be cast in the future (it's a community project so they don't usually exclude people). After this he wasn't cast in the next production and didn't get something to do backstage either because people refused to work with him as he was unpleasant. He kicked off after this rejection, insulting and harassing the directors and people in charge of backstage departments via text, social media and email, simply creating new accounts when he was blocked. He even stalked one of the girls until he was cautioned by the police. After this he went to some sort of therapy, when he finished he announced he wouldn't have anything to do with the drama group anymore, deleted everyone's numbers and left the group chat. This didn't last long however as he soon started texting people again and showed up to a performance simply to make people feel uncomfortable.
So far for the backstory, when the play for the next season was announced in the group chat, I received a text from an unknown number shortly afterwards. It was this person, asking if it was true that I was directing. I said yes and gave him short but polite answers about the auditioning process. He then started to ask questions about the script and started to badmouth other members of the group to me. I told him truthfully that I couldn't answer these questions because these things were only between the directors and management at that time. His tone had been friendly until then but after my message he asked if I was "always this blunt and hostile", because he was "just trying to get to know the directors". I ignored the message and he didn't try again. He probably thought we didn't know the backstory and it would be an easy way back in. He also sent us friend requests on facebook and was just very "in your face" which made me and my friend very uncomfortable.
Today we have received an email from this person on the "official" drama group address, where he didn't address me, only my co-director and stated that our audition dates didn't suit him, so could he come 30 minutes before finishing and we just give him a monologue there or send it per email. The audition process usually includes some improv and reading with other members of the group, so we can see how they go together. On these things we then chose a monologue for each person auditioning to learn by heart to perform in front of us. There are three audition dates and as a former member he should be well acquainted with the process.
AIBU to tell him that if he wants to audition, he has to do the same things everyone else does? And are we unreasonable to not want to include him at all because of his past behaviour? Personally, even without knowing the backstory, I would have had enough after him trying to suck up to me while simultaneously insulting me but maybe I am overreacting. How would you deal with the issue?
