Multiple WoW accounts on 1 Battle.net and RAF?

Not to my experience, because each game account can have it's own referral, regardless from the bnet account it resides under. So only 1 of the 4 and the new one will have the xp bonus, unless they are chain linked.

I have A-B-C linked & E-F linked, under the same bnet account. I've made a new G account (linked to C) under another bnet account. When I group ABCEG, then ABCG get the bonus xp cause they are linked, but E doesn't get the bonus despite being on the same bnet account.
