Can you limit resource use after some reasonable amount? Seems like you've got the tools for that already. "Network Firewall [...] + Web Application Firewall"

Can you limit resource use after some reasonable amount? Seems like you've got the tools for that already. "Network Firewall [...] + Web Application Firewall", "IP Rate Limiter", "Alerts to detect abnormal activity", etc. I can see why people don't want to give their credit card to someone they haven't made a deliberate decision to give money to, or to mix their social life with business. Edit: there's also the problem of trusting a company to hold onto your card data securely - I let almost no companies I do business with save the card details, and prefer to just type it in every time. Storing credit card details makes you a target, and I'm doubtful many smaller companies have the security skills to defend themselves. BTW, "software" is not a countable word. Instead of "softwares" you mean "software services" or something.
