Things are the same until they aren't. With what we've seen the last decade we would collectively need to say the probability of problems with a couple thousand at grocery stores during covid would be low and have to be considered a dramatic crackdown as compared to what they've allowed with various products in the past with amounts exponentially higher. Now, that being said, the guy doing $80k a month with GCM and cycling his credit limit is certainly going to get shutdown as there is plenty of evidence and data points to suggest that. Minding your own business and playing with the limits they set and staying far away from the line is certainly not fail proof, but it helps one's odds.
