This would be a perfect time for you to be the ambassador of AirlineSim and talk to the player.
Maybe the player doesn't know about the reset button, maybe they do, but why not talk to the player and find out?
Do report back if you find out what this is all about?
Well, I did contact the player as he set up yet another easily spotted account.
I asked if he needed any help and if he had any specific reason why he was multiaccounting trial accounts, and leaving them abandoned after the first day of usage.
First, I got a reply "wot".
Second I asked again if he needed any help, he replied he only has two accounts because other accounts are "expired" (hard to understand how they would be expired if they are still active trial accounts set up just a few days ago unless they were banned by AS already).
Well, I replied back saying that maybe he should contact support by email and straighten things out with them if his accounts are inaccessible, or ask me for any help he might need with setting up his airlines (e.g. resetting, etc.)
He replied back that none of the other accounts were his.
So I replied back that it was hard to believe, having the same account being a modification of the same username, e.g. john.doe, john.dooe, johndoee, john..doe, etc.
Finally he said those accounts were his and asked how much it cost to become premium which I pointed him to the page to buy credits, copying a direct link for his convenience.
To which he asked what was so "bad about doing it" to which I replied that it was prohibited and this was a very clear case of multiple accounts by one person.
*At all times I did present myself as a player trying to help him out and repeatedly asked him to email support to explain his situation and try to help get things straightened out, to inform support which one was going to be his main account and which were the others and ask support the other accounts be eliminated, I even offered to help him understand AS better (* I make this note in case someone tries to make unnecessary remarks to this post, YKWYA).
We did exchange couple of messages back and forth, he asked me if he can give accounts to other persons, or if I can ask support to eliminate his accounts. To both questions, I gave negative reply and insisted that he contacts AS support ASAP. In all messages and replies I always asked him to email support and repeatedly included support email address. At the end he just replied Cheers, and that was it. We'll see where this goes next. So far I do not see any of his accounts being upgraded to premium.
