For me, it would have to be: TotalBiscuit - Because he's a very rude, uptight asshole to his fans, and he's even been rude to me personally on Reddit, Twitch and Twitter in the past, often without me actually doing anything to provoke him. Pertemps - In short, they headhunted my recently updated CV and offered me the chance to go for a £16k salary customer service job, and expected me to either spend £90 on a train/bus commute to attend an interview between two night shifts which I couldn't reschedule, or withdraw my application. Because I wanted this job, I went. Unsurprisingly, I didn't get the job because I was significantly sleep-deprived, fatigued from a three hour commute, inexperienced, ill-prepared and somewhat nervous, and had to compete with about 20 others who had years of customer support experience. It wasn't even that which was why I won't do business with them now, but rather how callously they handled the rejection by phone and just rudely brushed me aside like I meant less than nothing to them. Reed - I only use their website for finding work because it's genuinely the best around, but I would never use them as a recruitment agency given how much unwanted spam I actually receive from their recruiters. It's so bad, I've almost considered reporting them to a spam watchdog.
Oh my God fuck TotalBiscuit actually. There was a thread about him on Reddit recently, and people were telling him that they hope his cancer kills him and stuff. Which is horrible to do. In fact, one user explicitly said "No one should ever be told to succumb to cancer and die." Which is true. It's also HILARIOUS because Totalbiscuit did exactly that four years ago. Of course his response when this was said back to him was "oh man, what did you do to make me say that to you," which actually makes me mad unlike most internet responses. And of course, when this is brought up on reddit the response immediately become "well what's the context, we need to see that!" But I thought you just said that no one should be told to succumb to cancer. Beyond that he supports gamergate and is a huge hypocrite that is only a "games journalist" (HAH) when it benefits him, but he isn't one when people start bringing up evidence about that. tl;dr: gamergate sucks, twitter is toxic, don't make cancer jokes, games are stupid.
My hands are tied when it comes to Gamergate, actually. I've seen people get doxxed and swatted on both sides of the debate, and I really hate the harassment directed towards Zoe Quinn and Anita Sarkeesian. Also, there's that smartass post TB made on SomethingAwful where he proclaimed that he was, and I quote, a "23 year old Law graduate with an IQ of 155." I did mention the whole 'get cancer and die' thing too before I edited it out of my last comment, but that wasn't a personal reason I stopped watching TB's videos or following anything to do with him. My dispute with him was before I was even aware of the cancer incident.
