It's absurd to complain about info of a game that:
1- It's public data.
2- It's not personal info.
3- It doesn't belong to you.
Well just my 5cents about this...
I think its not about if its personal or not. When you browse any webpage, use flash or some other programs, you have the right to refuse/deny/prevent those softwares about getting (and specially storage) any data comming from your activity, in whole EU since 2011. As far as i know thats why you are getting "cookies consent" banner in every single webpage, doesnt matter if its a pacman flash game, a VOD platform, or the National Health Service..
1-Its public? not at all, its private. Maybe you dont have the rights, but thats doesnt make it public.
2-Its not personal info? Its not, but i think thats kinda out of discussion, if its about personal info, this guy would have the cops knocking his door right now, however before someone use 'your' (and its quoted on purpose) data, personal or not, there should be .. somehow.. a constent.
3-It doesnt belong to you. Well .. thats the controversial part , as we are not allowed to discuss about laws, i dont go further, btw.. realice that even if you sign a contract rejecting some of your legit rights... that part could be unlawfull and you could still demand them.
What about a consent option onthe program, and make it only able to upload the self data instead group/ally on? that way only people who actually agreeded about uploading their data would have it there .. and no one could feel injured about it.
But i guess that could make those website lose visitors or smth?
