In this kind of thread, it is very common to see some boast of their high English proficiency and criticise others by looking down on. However, in reality, most of them can't speak English at all.
What they want to do is to look down on others and enjoy the feeling of being superior. To prevent them from being rife, using English could be one of means.

こういうスレだと俺は英語達者だって言い張って、他人を小ばかにしまくる奴が常に出てくる。だけどそういう連中のほとんどは、実際には英語ができないんだよ。見下していい気になりたいだけでね。
そういうのを防ぐために、英語を書く意味はあると思うけどね。

Disclaimer:
If you want to correct my English, it would be appreciated. However, pls tell me where and why. I have met many "hit and run" English teachers(probably, many of whom are not good at English in reality).
