> The particular "changes" introduced by the teenager editing Scots wikipedia are very much unnatural, artificial change, and one that is done in a systematic way, "erasing" (by ignoring, simply due to the author not knowing the language) the actual Scots words and replacing them with calques from English.

You say that like that isn't a ubiquitous process. Copying the usage of someone who was unfamiliar with some other usage is... almost the entirety of language change. The rest of it is copying the usage of someone who was being deliberately weird.
