A long time ago I entered a contract with a company called "Immanitas" whom I now believe may be a fraudulent company. They sold some AI Roguelite steam keys to various 3rd-party stores/websites and haven't yet paid me the agreed share of profits, even after almost a year of reminding them.
Today I banned the Steam keys I gave to Immanitas and which made their way to those 3rd-party Steam key stores. This ban is not retroactive, so if you already purchased from a 3rd-party store and activated the key before, then you're fine. The ban also doesn't affect you at all if you purchased from the actual Steam store.
The 3rd-party stores might take some time to realize the keys are no longer working before de-listing them as purchasing options. In the unlikely event you were one of the unlucky users who bought from those stores before they de-listed it but after I applied the ban: Please first reach out to the store, tell them to delist AI Roguelite because the keys were deactivated by the developer, and ask if they'll give you a refund; if not, feel free to email me at [email protected] with the Steam key you got and the store you purchased from.
