@Sperver Thanks for considering it and for your
valid questions.
how those bb-codes will be implemented into posts. Has this to be done manually or does it happen on the fly?
The [adblock_hide] is a manual BB code, in the sense that it won't hide whole or parts of posts automatically (at least not in the current version).
It can be extended thought, either in a future release or by other add-ons. It'd be as simple as putting the whole message contents inside that BB code before rendering it.
Do you have any example criteria you'd find useful?
One from the top of my head, would be to hide a whole post after it gets a certain amount of likes. The number of likes is a good indicator for the message popularity or its usefulness (meaning that it would probably be worth disabling an ad blocker to be able to see it). Maybe you think of something date related?
If it´s done automatically via the system, do I have control in which parts of the site I´ld like the rules to apply? For example: active in gallery, but inactive in posts.
The current version only supports hiding content in thread posts. Not in the gallery, the resource manager, or the conversations.
Is the gallery the content type you'd like to see supported next?
how do search engine interact with those bb-codes? For example: is the GoogleBot recognized as using AdBlocking-software? Will a SE-bot see the page different, as a user without adblocking software (regarding penalties for cloaking or DC)?
Modern search engines can and indeed do
execute client JavaScript. As far I know they don't use ad blockers and they wait around 5 seconds after the page loads so they should see the full content.
Search engines aren't specially treated, so I don't think there's a risk the pages get flagged for cloaking.
