Servers banned from Master Server
Servers will be banned from reporting to the Master Server if:
1. they have gameplay-affecting modifications (without using a modified protocol), and/or
2. they use unvaried map rotations, and/or
3. they are noted by multiple AC forum users as being undesirable in some way, eg. constant offensiveness/abuse by admins, and/or

Yes, you have to provide sufficient resources for your server, for example bandwidth and computing power.

Yes, you have to properly maintain your server, for example, check uploaded content, update existing content and yes, check, if provided content is properly working.

Yes, you have to continuously keep maintaining your server. Read the log files, check if everything is working as desired, check, if updates are available, check your inbox, if someone tried to contact you...

Now, if that was really news to you, and you can't accept it, please remove your server from the list, so we don't have to do it...

In times of old staff there appeared some "crappy" (bad quality) maps, like EzjemVille etc. Crappy maps were played by some, the same part of players, which played almost the whole time the same a few maps. So crappy maps competed with good quality maps and started to dominate over them. This situation annoyed old valuable players, which stopped to play AC and new players didn't come, because AC wasn't already attractive.

So old devs took a decision, that servers with crappy maps in maprot should be banned in master server. In short time that brought quick growth of players amount, what was caused by increase of playing good quality maps.

Later this practise was abandoned by newer staff, what among other things caused considerable decrease of players amount to current state. So high time to return to old, proven practice and ban servers with crappy maps in maprot. That needed rules change, what happened.

The problem is especially with these servers, which have up to several maps in maprot, where big part of them are "crappy" maps - such servers for sure will be banned. List of forbidden bad quality maps in maprot and servers threatened by banning is given in the first post - if their maprot won't be changed, they will be banned in master server.
Note: list of forbidden maps can be updated.
