The examples in the article sound like the vote count was reasonably accurate. (When someone against attends the vote count at their precinct, and says that it was 400 for, 25 against, and the official total says 86.85% for, that's probably an un-finagled tally - unless the ballots were stuffed before the count.)
"Dissidents, who were divided between those who advocated a ‘no’ vote and those who called for abstention so as not to legitimize a process they deemed a fraud, reported a few incidents across the country of members being temporarily detained or harassed."
I mean, it still shouldn't happen at all. But you could detain a million people and it wouldn't be the cause of an 85% yes vote among 8 million people.
You can even see evidence of all of the above on Youtube, but nobody gives a shit, because nobody believes anything can be changed. Heck, most people don't believe anything _should_ be changed, because aside from the brief period in the 90s (of which the US "cured" Russia by directly and openly helping Yeltsin secure a win in a runoff election), that's the way it's always been there.
Heck, with the recent ballot-related shenanigans in Broward County FL and elsewhere, I'm not sure everything is 100% sanitary with this stuff in the US either anymore.
And in case the downvote brigade thinks I'm making this up:

I have no doubt that vote stuffing happens in Russia and many other countries, but that doesn't mean it's happened in this election.
