As a person who understands Russian, isn't it obvious to you that the user highlighted the text to specifically indicate that these are not his words? Even further, he comments on this text, says that it does not work out that way. At the same time, it is obvious that he does not even have specific Russian alphabet characters on the keyboard to write all the words correctly.
Since when has font highlighted been an indication that the text has been copied? Show me it, poke your nose.
I see the copied text without providing a source. In that case, let's voice this rule to everyone.
Are there any privileges for this account?
Well, actually, mprep once said that:
IMO as long as you can relatively easily discern the fact that the content in question is not original, it should be fine.
In this case, this is just such a situation, IMHO.
