well it seems you are a new reporter thank you for your time and your will of busting hackers.
so to make sure you wont get disappointed lemme make this clear for you,
if your trying to find a fog click make sure of 2 things:-
1-not host respawn, switch,pick bug
2-clicked while not in fog then went to fog and the click remains which is like in your reports
as in this and all other reports if u can check again u will see that he clicked on bloodseeker before he went into fog, after he entered the fog the click remains so its not a hack.
a hack when he clicks on someone that is not seenable and totaly in fog.
hope im clear enough..
