(Taken from https://easylist.adblockplus.org/blog/2 ... ite-admins)The user must be the only one in control of the filters required for the purpose of the anti-adblock message. It must not be possible for external sources to add, modify or remove any rules remotely.
The site I believe to be in breach of these rules is www.refunder.se - a user at AdBlocksend us an ad report which contained the following custom filter list: http://www.refunder.se/adblock/filter/abp which I immediately investigated.
This could be a breach because they are able to update that to add more whitelists or change it at their whim, not at the user's decision. Even adding blacklists for competitors (which would be a really bad idea causing more hassle for all of us).
