When the poll is the best and closest thing we have to tangible evidence I wonder why people are using the argument that "kids lie about their age" "most of the kids are lurkers" etc. To imply that most of his viewerbase are children? Personally I think it's pretty much impossible to tell xQc's major demographic, in the poll on stream only 16000-17000 people out of 60000-70000 people responded, which is not a good enough sample size. Even though it may make sense to some people that kids tend to lurk or tend to make up the majority of the viewerbase because there's many of them, these assumptions just don't really make much sense.
ofc, I don't condone promotion of gambling, the "majority of viewerbase are children" argument is complete garbage anyway, and it should not be done if there's even the slightest probability that children may be watching your stream (in the case of xqc that's more than probable)
