Well, ok. (unzips)

Stability of those fps are even more important. Modern games have problems with that.

Have you ever seen this behaviour anywhere? Ban is ban and has nothing to do with messages. At least I never saw or even heard about any forum/whatever to remove all messages while banning someone.

Did Reddit ever claim to remove threads and comments while banning someone? No. What did you expect? People are actually actively seeking for methods to remove all their messages and here you are: “People! Reddit doesn’t remove your messages when ban you!” Yes, we know.

I never stated that it is useless. I said that natives might say the total bullshit and do that with a poker-face being absolutely sure of their correctness.

But keep in mind that native speakers might have an even worse understanding of grammar than foreigners: most locals speak intuitively and never care to actually study their native language.
