Welcome to the automated account suspension age of the internet, where companies shoot first and don't care later, as the amount of false positives is not worth putting any meagerly (if there's any already) real, physical support to resolve. This can apply to smaller companies too, for other but equally pricey reasons. The amount of fraudulent activity attempts online may warrant those aggressive measures from their business perspective (that are also not limited to passive data collection, but taking active steps such as scanning targets' ports [0]).
Unfortunately, if you live in certain areas or are forced to use mobile networks, with IPs constantly refreshing multiple times a day, major services can be almost unusable, and the user may not even realize the reason why. Some—for reasons I'm not knowledgeable about—do it better than others, but it may simply be about the resources put into it and the amount of risk a miss could amount to.
