I disagree
When saying that 7 players of a particular club have tested positive they in affect taint every player in that group.
And as has been said it is an open secret who these players are so the actions of 7 have definately invaded their privacy.
If it is an open secret how did Seven invade their privacy then? Their privacy had already been invaded.
Saying that 7 players from club x have tested positive, still isn't a breach of privacy laws because from what was broadcast you still can't identify who the 7 are. Yes it taints every player at that club, but they can't be identified, they are more considered "guilty by association".
