Thank you for the prompt response and agreed. For clarity, I am not seeking any refund or action to be taken in relation to my own losses.
However, they are advertising these services on Itch.io and i think it is important to try and protect others from this behaviour. Not sure what can be done exactly- but i would hope steps can be taken to prevent him from fishing for victims via this platform.
I have sent an email to support@itch. Hopefully they will look into it.
Even if no action is taken - which would be a shame - I'm satisfied I've done my bit by trying to make the appropriate people aware.
