Ratings for lost films = fake accounts (even top 1000 voters)
Every once in a while there is some post raising the issue of fake accounts and bots.
In many cases it's hard to judge, but I found some crystal clear cases that need investigation.
I checked 4 lost films that should not have any vote but I found that they were rated also by few top 1000 voters.
Top 1000 voters should be serious people who watched a lot of movies, not trolls inflating their numbers.
The movies I checked are:
Gentleman's Agreement (1935) with Vivien Leigth -> rated by 47 top1000 voters (166 total ratings)
Her Friend the Bandit (1914) with Charlie Chaplin -> rated by 27 top1000 voters (269 total ratings)
A Woman of the Sea (1926) by Josef von Sternberg -> rated by 7 top1000 voters (63 total ratings)
4 devils (1928) by FW Murnau-> rated by 31 top1000 voters (224 total ratings)
I'm sure that checking other lost films would result in the same findings.
That can be a good way of finding and cleaning at least some fake account.
