I agreed to the TOS, but I don't know what I agreed to. Links and definitions would be really helpful. I found this page which is similar and relevant, but slightly different.

Unfortunately, still no definitions.

Not Allowed

• Mirrors/Userbots << what are these?

• Torrent Aggregators

• Crypto Miners

• Hosting/Distribution of DMCA protected content

• Music Bots

• VNCs/Virtual desktops

• ToS Violation (Card Testing/Hosting Card Testing Services) << what?

• Suspected card fraud / Payment dispute

• Trial Plan Abuse << for instance?

• Phishing

• Sending Spam

• Anything Illegal

  I would be more comfortable deploying stuff if account suspension with some sort of dispute resolution was cited rather than only mentioning banning.
