Even if someone is not attempting to break the game, they might accidentaly hit those rare edge cases.

Of course, you could infer the usefulness of the increased volume of feedback from the fact that a game author is extremely happy about it.

Overall, I don't see any particular problems with having reported issues. We definitely don't pay cloud storage per open issue or anything like that. Initial assessment of a bug report is not particularly difficult either.

I'm not sure if your concerns translate to actual negative impact.
