I can think of several negative attributes.
Piracy, Hackers/Identity Theft, Overused Memes, Troll Trending, Youtube Tryhards
Piracy - Hurts developers and musicians, large or small scale. Downloading music for free is now widely regarded as a normal practice.
Hackers/Identity Theft - Self explanatory. Obviously not all Hackers are bad but some of them have a God complex. Not to mention that there is no such thing as Hacker ethics so for the most part, normal people fall victim to their crap. Identity Theft is the extreme example of a hacker going too far.
Overused Memes - Also self explanatory. I like the occasional meme myself, but when people spout the same garbage over and over again, it becomes less and less enjoyable. What's worse is that these people think they are being genuinely funny.
Troll Trending - You ever notice how it is now fashionable to troll? This is going to sound a little weird, but I'm a firm believer in Troll purity. I believe a real troll would never identify themselves as such or say golden phrases like "I'ma going to troll this game for a bit, lol". Trolling is not supposed to be contrived or obvious, at least if there is to be any real effectiveness. But now, there is a strange sort of trend where trolling for a little while is cool. This wouldn't be such a bad thing if they actually did it the right way. There is no shock factor associated with trolling anymore, aside from the occasional over-sensitive/easily angered type. Like memes, I think this is done by people who believe they are being genuinely funny.
Youtube Tryhards - My god, does internet entertainment suck the big one. I actually find myself longing for better TV as a means of escaping some of the terrible yet somehow popular Youtube personalities. This doesn't stay within the confines of Youtube either. Sites like That Guy With The Glasses is the worst culprit of poor entertainment. I'm not object to Doug and Spoonies stuff, but ever since it became "Doug and Friends" it's been one shitty reviewer after the next. People who have no position being in front of a camera at all. Not because they aren't photogenic, but because they have no concept of pacing, editing, charisma, or engagement. Yet these are the same people who criticize movies or games for being less than perfect. Pot calling the Kettle black anyone?
