I think it looks more like poverty than addiction.
Many of these appear to be squats, so once food/shelter has been sorted I guess the next on the list is an internet connection or console.
That most also appear to live in their own mess is possibly depression at their circumstances, I'd guess washing/cooking facilities are not common in your average squat either.
The sad part is that we are probably looking at some kids bedroom and his day job will be some menial role in a kitchen.
Third one is clearly IronWarrior's basement.
Erm, there is clearly BOOB in that, quick hide it before a UB sees!*
*lol.
I think at least some of these are staged, specifically the ones with "timestamp" notes to various chans.
