<prompt> Human: Woke up to emails from two of my credit cards two different banks announcing that they had raised my credit limits to approximately triple the previous limits. I didnt ask for a credit raise not complaining either and I havent changed anything recently--no salary raise, no loans paid off, no major purchase, etc. I have zero debt and pay my cards off every month and have done so for several years thats not new either. Id just like to understand what may have triggered this unexpected adjustment, especially since it seems a bit strange to me for two different banks to have done it at the same time. Do I need to pull my credit reports and see if something badweird has happened there?  <response>: because they dont want you to pay it off every month.. they are hoping you overspend
