I refer you to the AMA, MLA, NYTimes and Chicago Manual's of style. I suspect that in your google search you chose a 'wiki' guote in preference to these style manual's because the 'wiki' writer describes common usages, not correct grammatical or stylistic elements.

'Aint' is also common usage.

The style manuals do not agree with the 'semicolon solution' that www.grammarbook.com suggests for handling lists with commas imbedded. They prefer to include the preposition in each of the listed locations: .... from Moscow, from Springfield, California, from Alamo, Tennessee and from other places as well.

There are distinctions between elements of grammar and stylistic choices and they are complex. My original comment was in specific response to 'Caring's sentence -
"The implication that suggests some of the highest ranked officials in some communist nations have stolen the wealth from people is interesting; that especially in the country where there's such a crackdown on corruption."
