The reason sounded: "For plagiarism, or spam from the account." There was definitely no plagiarism, all this is personal thoughts about certain events. If this was regarded as spam, then I would like to find a solution.
It says
probably banned for plagiarism as that's what most permabans are issued for, but probably is the keyword here. I can't find any reports on you in the report queue but there was a post in the staff forum about spam on the 12th of December and I'm guessing that was what you were banned for seven days for. Maybe contact a Russian mod and see if they can shed any light on it.
