There is a long thread on the Chase forum about shutdowns. Other than a few short threads, and several comments about AmEx FR for total spending in excess of what they think is appropriate, I couldn’t find anything similar for AmEx or Citi or Barclays. Curious as to general thoughts about how aggressively these other issuers shutdown accounts specifically related to MS and payment from multiple sources (rather than due to churning).

Basically, I’ve been a minor MSer in the past, and always using a card with plenty of other spending. Now thinking of REDcard 2K - 5K per month on non-Chase cards with little or no other spending (to take advantage of various total annual spend bonuses) and wondering if and how quickly I should expect a shutdown.

Thank you.
