im not a hacks mod but I checked this because your report was good, with many situations included, but he is clear.
in the beggining he stayed behind because you harassed him and you had bara in team so he just played safe.
6:53 He saw you leave mid.
12:30 He autoattacked void, I think he was watching something else on map - it was a fail he could've easily killed void and then go invis. He went invis when nessaj showed, not while he was in fog so nothing suspicious.
10:35 nothing suspicious- they wanted to gank brood and he came by low hp bara who was in forest.
22:15 if you claim you watched replay, you probably saw he passed that way 2-3 times before he scored. He was just hunting for kills blindly and he was just lucky this time you were there, past 2-3 times nobody was there.
other situations are clear as well I just didn't note them down, he was just waiting and hunting for kills, I guess he wanted numbers because its new account, but he is clear.
PS: Anyway I deduced all of this just by watching replay, I didn't use any programs hack mods might use, so they may find out something I couldn't and I am wrong.
