And AFAIK evilslut is not on the forums, so how did he know I denounced IAHM's blocking?
Because someone told him.
The forum is publicly visible - no need to register or log in to read what we write here.
I'm afraid it's in his best interest to give a statement now, otherwise people are assuming the worst.
And then?
I'm afraid we have an entitlement issue here - several people feel they have the right to something they do in reality not have - and that leads to clashes (and before anyone asks, I don't do MP at all, I don't know who administers the servers, I have hence been in contact with no server admin and I have also not requested or suggested to MP server admins to act in any way).
There is no right to use MP infrastructure - that's a service voluntarily provided by individuals. Just like there is no right for me to log into your computer and run my calculations there - it's your computer, and I can only use it by your permission.
There is no obligation of a server admin to distribute this service equally, independent of political considerations etc. - which is to say, if you allow me to use your computer, it doesn't mean anyone can on the grounds that you already allowed one person and you have to be fair.
There's no right to a statement by the server admin - you don't have to explain to everyone why he may not use your computer.
So there's no one taking away your rights here. Please get real and face reality. Asking nicely is far more likely to restore your access than demanding statements or else...
You can start argue what ethics demands in this case - then we'd have to first agree which type of ethics we're going to use ('ends', 'means' or 'virtue'). In all cases, we'd have freedom of the admin and property rights pitted against freedom of the user, and we'd have to come to a hypothesis what the cause of the measure might be, and whether it can be justified. It matters a lot what weight you give to one type of freedom, how you value property rights - so there's no one answer ethics gives, it's complicated as soon as 'ethics' doesn't mean 'my ethics'.
In my opinion a server becomes "official" if it is resolveable as a subdomain of flightgear.org, and/or if it is announced as an official one by the flightgear wiki.
Pretty much everyone can edit the wiki. You could declare anything official infrastructure by the mere expense of making a wiki entry. Doesn't fly. I think the first three words of your statement are the key here... As for the domain, that's also privately owned and paid for. See above...
