But I can tell you with 100% certainty that he isn't.
I know him irl and the most shadiest thing about him is that he's some 15 yo kid that instead of partying and fucking girls like teenage boy should he stays home on the weekend to play world of warcraft.
I can't say what happened in these vids but accusing someone to DDOS because you had an disconnect in one of multiple games like you said yourself is quite a stretch. Accusations like these can ruin the reputation of a player even if they aren't true.
People are quick to hop on the bandwagon, maybe you should take a minute to think if that's the right way of approaching this especially doing it publicly and without any evidence. A video of you having an disconnect doesnt qualify as such.
