Based on my reading of others' stories, Barclays might shut you down if
- your account received push-kind payments (bill pay via whatever sources,
checking account push payment)
- you opened new accounts recently and caught their eyes
- you contacted CSR and your account was reviewed simultaneously
- you went over your credit limit and caught their eyes
- your spending did not match your income
- you mailed MO to pay your credit cards
"Barclays seems to do this once they have put eyes on your account. And once
they see any old or current MS activity (most of these people say they had
bought GCs at some point with their Arrival etc) they zing ya. Even though
there is nothing wrong with buying Gcs, Barclays seems to not want to let
you have the points from doing so. We have all seen this stuff before."
