It's just awful to read, it's the forum equivalent of people writing their name in shit on a toilet cubicle. Quoting proper sources and something which will add to the discussion is fine, but what they're doing is different. They're purposefully spamming threads with unfunny memes and quotes from people on Twitter with 8 followers, not in the attempt to do anything other than dominate threads.
These things aren't even meant to add anything positive. They aren't attempting to do anything other than drown out people who they don't like. It's taking obfuscation to extreme levels, their only attempt is to spoil threads by bombarding it with ugly shit.
The mods and owners here have to decide what they want the forum to be. When people remember ESB or the early days of CHB, they don't reminisce over the times when losers spammed the forum with shit memes. If they want CHB to be a discussion forum which promotes debate, they have to make a stand against this, otherwise the forum will just die because good posters don't want to see that shit. It's like going to a public debate and having the clown sat next to you fire off their airhorn whenever the person they don't like starts to speak. It's childish and goes against forum etiquette.
