Oracle Suspended My Account

I don't think OP mentioned using a VPN.

But even if they had: really, managing a cloud infrastructure via VPN is so far from shady that it's often recommended or required by many tech companies' security policies for people working from public wifi locations among other circumstances, as an added layer of protection against local eavesdropping and sometimes also for specific predictable networking routing within a cloud network perimeter.

I realize that OP is acting as a student/hobbyist, but there's no inherent reason why someone immersed in best-practice tech culture would necessarily be shady if they applied this VPN recommendation to their own personal tinkering. Many of the benefits of using one still apply.

It would, of course, be shady if Oracle intends to deny service to people in Turkey and the VPN use is to circumvent that restriction. But I don't believe that there is such a restriction on place.

From what I found, people using the free tier often get their instances terminated and other resources removed and reclaimed. The suspicion is that there are some automated systems that when capacity falls below a certain threshold, they will take back resources from the "freeloading" users. (For the humor-impaired, that is tongue-in-cheek.)

This is well within their right and ToS say they can do this. Nobody should be surprised or annoyed that they do.

I've read reports that entering your billing details to sign up for a pay-as-you-go account will reduce but not eliminate the likelihood of this happening. You still get the always-free resources but Oracle's systems see you as a paying customer, on paper at least. This is what I did and I haven't seen any disruptions in the 6 months I've done so.

In this case, however, since the whole account was suspended it sounds like the author probably got caught as a false positive in some kind of automated fraud-prevention system.

Just imagine living in America in 2003 with 9/11 fresh on everyone's minds. Were you there? Do you remember the mindset of adult Americans in 2003? What did the US military do in 2003? What did the average CNN-watching American feel and want? I remember well. We wanted to bulldoze Saddam Hussein and his "Axis of Evil" because terrorism. We wanted to raze Iraq to the ground as revenge for "harboring terrorism" and "WMDs" which were about to be unleashed upon our friends. Americans were in a complete frenzy, psychosis, and out for blood. Do you remember? I remember soldiers wanting nothing more than to "take out those stupid rag heads." Did the occupation ever end? Did Iraq have anything to do with 9/11? Did anyone suffer the consequences of the invasions back in America besides the Americans killed overseas? Do you think Russians are not actively being brainwashed by their government to support a war like the Americans were for their wars? Think again. The media is more powerful than ANY WMD because it perpetually and incessantly corrupts the minds of its viewers.
