How would FAF not be liable for some information issue here?
- have made replay information public for everyone
- have made a parser to allow you to, uh, parse this information and even included instructions on how to use it
No idea about Europe but in the US there is a liability doctrine that doesn't let you just give a person tools, say "don't do that bad thing with the tools" and then wash your hands when you put zero effort into making it difficult to actually do said bad thing.
The only thing FAF hasn't done is give you step-by-step instructions on how to download replays from the vault to then use the tool.
I mean I don't get the issue in the first place, do people have legal ownership over the words they write in game or something? Wouldn't this already make the replay vault a "legal liability" unless you requested consent before publishing any replay?
Also, "You are not allowed to analyze single person behaviors or do a social rating and publish this (or basically do anything that relates back to a single user)" isn't this essentially what moderation does? Don't report results get reported back to the person that made the report? That's a publication of the analysis of a singular person's behavior.
