Actually, using a purchased file to test download speed isn’t a common practice—there are built-in tools for that.
I understand that occasional redownloads happen due to internet issues, and if we were talking about 3–5 times, I wouldn’t even question it. But 89 downloads from a single IP? That’s not normal buyer behavior.
I appreciate that you want to defend buyer rights, and believe me, if this were one genuine customer struggling to download, I wouldn’t raise the issue at all. However, as creators, we have to protect our work from abuse because repeated unauthorized sharing means lost sales. If you’re not a creator, you might not fully see why this is a concern, but for us, it’s a serious issue worth investigating.
And to clarify, the downloads stopped because I unpublished the game—not because the buyer suddenly solved their issue.
