I'm saying that free services are easily abused because of the lack of up front cost and ease of forging contact info. You abuse a service, the service is terminated, you got to utilize it for a while and suffered no penalty aside from having to sign up for a new account. You use a stolen credit card, the service will be terminated and now that stolen credit card can be reported for abuse as well. A legitimate account that is paying for service and has legitimate contact information can actually make contact and rectify the issue, clear up a misunderstanding or be made aware that their domain is being abused in some way. I signed up for Sendgrid a few years ago for a company that I worked for and we used it to send the company's first newsletter to 300,000 users in about 14 years. About 70,000 of those bounced and somewhere shortly into delivery process, Sendgrid halted it and called us demanding to know where we got our email list and insisting that we verify user information for multiple addresses that had bounced. Once we explained the situation and verified everything, they released the halt and that first volley continued creating records for which email addresses we shouldn't be sending to again. Everything was fine from that point forward...but even with a paid account they were actively working at fraud prevention...and as long as there was a legitimate contact on the account it was perfectly reasonable to get resolved.
