Third is that even people who are only spamming can be fine for forum and if they leave here the forum may lose a big part of its users and its popularity.
No, you are not fine for the forum. If you leave here, nothing of value will be lost. Posts like that one are exactly what I'm talking about (I couldn't even understand the rest of it).
I second this. That whole post is a big load of horseshit disguised as a long, pseudo-constructive post. People here don't like their English language skills criticized, but so many of these garbage posters only know so many English words that they rearrange about six of them in different combinations for each topic and try to pass that shit off as a good post. Someone here with more motivation and less laziness than me ought to do an analysis of shitpost content.
