ok basically d0cc is dutch guy who has been streaming for months, dude is insane, he gets in to FPL, catch is he doesnt speak and as a result is removed from FPL
"d0cc" or who we think is d0cc starts to speak during streams, "d0cc" later tells us that the reason he didnt speak previously is because he was embarrassed of his voice. this is when d0cc states on twitter that the person viewers were hearing is d0cc's friend who watches his games and gives information for him, so this makes people wonder why d0cc doesnt speak in the first place.
d0cc explains that his parents are super strict and dont want him playing CS or streaming so he has to do it secretly, talking to himself would obviously give it away. not because he was embarrassed because of his voice
ChrisJ invites d0cc to come to his place/go to him to prove himself as at this point a lot of people are beginning to accuse him of cheating as the whole situation is getting suspicious. d0cc of course refuses when anyone in their right mind would jump at this chance.
d0cc streams at his friends house with a webcam/mousecam to prove he is not cheating even though this proves nothing
(i wrote about this up top) when VAC wave hits, d0cc's parents BIOS lock his computer apparently even though they clearly have no idea even what a computer is. he also says he cant play for 6 weeks, next day, he is streaming. more suspicion.
tldr; d0cc is shrouded in lies and mystery and is probably cheating
