For the Americans in the audience: if this story of fraud gives you pause and you want to do something to help...
Most places in the country are positively starved for judges of elections (who are local administrators, one per polling location) and the rest of the elections team (who both manage the mechanics of the election and serve as an observer / check-on-power for the judge). If you want to help, it is a two-day time commitment per year, and the job and responsibilities are extremely straightforward.
You can often get yourself elected (in most states, these positions are elected but nobody runs for them so you can write yourself into the job). You can also reach out to the county elections office and volunteer; the positions are so chronically under-staffed that they're usually extremely thankful for volunteers, and when nobody is elected to the position in a given voting location, the county has to pull from volunteers to appoint people to the task.
You get a chance to meet all your neighbors, and there's no better way to ensure your vote isn't stolen or compromised than to secure it yourself.
