But someone who can't write proper sentences in English won't write anything interesting because 1) the sentence structure will be broken, and 2) they won't have vocabulary sufficient to create an interesting post. I have seen this hundreds, nay thousands(!) of times. And in addition, they're usually too lazy to put any effort into what they're doing. I agree with your sentiment, but I think it'll take some time before the shitposters get discouraged and give up. But I'm patient.
They don't even make the effort to get the title of their threads readable. And when they are readable it can be even worse.
I've seen things you people wouldn't believe. "Bitcoin to the moon" off the shoulder of Orion. I watched "Could bitcoin reach 100.000$ ?" glitter in the dark near the Tannhäuser Gate. All those threads will be lost in entropy, like tears in rain. Time for merit.
