I don't really understand what it is you said in your thread, but I think I can at least address the question of the thread's title.
What's the rule on friends and siblings? Well, let's think about it - how else do you think people get here? Of course it's encouraged to bring in friends and siblings. But if it's feeling like your friends, siblings, friends' siblings, siblings' friends, and so on, have not been getting a warm welcome, it may be because forum members have a bad taste in their mouths over some of the nonsense they've been seeing with regards to you. You've not had a very good track record with the people you've brought here, and we worry your friends will just dig it all back up again, which is something that is not wanted or appreciated. Whether or not any of this would actually happen, it's guilt by association. And that might not be fair, but that's just the way it is.
But if your friends, siblings, and etc. are able to behave themselves, just like anybody else, why WOULDN'T we want them here?
