A week ago I bought a FreeBSD VPS and paid with US issued credit card. After I realized that port 25 is blocked I've opened a ticket asking to lift this restriction (I googled the issue before I've opened the ticket so I was kind of aware that they might require a scan of my CC). 30 mins later, they've opened the port 25 and sent me this link.

Long story short, it's $5 per spam email that you send, but only if you are liable.
"you agree to pay VULTR.com liquidated damages of five-dollars ($5.00) for each piece of spam or unsolicited bulk email transmitted from or otherwise connected with your account,"
"If customers server was compromised (hacked) and then subsequently used for spamming this clause will not apply."
