Web browsing is far more of a threat with me. I only have factorio and Civ 5 installed and I can only play them for a couple of hours per week, max. I don't allow myself to play any game but those. Even after deleting my Youtube account, I can spend hours browsing it not logged in. My reddit account is on the ropes, all my saved stuff deleted, all subreddits unsubbed, stopped moderating most subs, and have stopped browsing reddit.
Browsing 8chan and dailystormer is my latest addiction. But I think i've taken a step up, if I had to interact with 1 more reddit retard I think I would do something terrible.
