I think that it is fair to assume that AA does its best to connect FT handles with Advantage accounts. I'd do the same in their position.

Not sure if this means anything, but Twitter does not discourage multiple handles. I have two primary personal accounts: my @XXXXXXX account is professional me and has a large number of followers; @help4XXX is where I try to get customer support and has very few.

IMHO the community is what keeps me here on FT.
