Sorry for playing the devil’s advocate here, but those 2 screenshots really do not prove anything. Anyone can make the first one, especially if it is an alt account just revisited very recently. I find it shady to have the name deleted and not that very forwarding. SG can verify whether it is really true or not based on the name alone.
As for the 2nd screenshot, it may not come from the same player who scored zero. A lot of players have posted here with similar loot reward and its also possible that the same can be obtained from various sources, i.e. Line, Facebook, Discord or other platforms.
Nothing in the screenshots can be inferred or attributed to the same player.
I am not saying you are lying. Just pessimistic as to the veracity of those screenshots. If those are yours, can you use some video recorder and post a video clip of that same account showing the player profile, the zero scores in the top attacks and top total on the already concluded mythic titan event, as well as the loot rewarded from the recent activity screen, all in one short clip? Thank you so much.
