There is a user who managed to get sort of protection provided by the "serial" script so that their posts regularly get a portion of undownvotes when script kicks in (Reputation tab in the user profile shows steady stream of undownvotes that happen daily at 03:00).
To avoid misunderstanding, my downvotes appear going through just fine, script seem to punish other community members.
The thing with the user is they are known to post from multiple duplicate accounts when their main one is suspended. And their posts from duplicate accounts typically collect massive downvotes.
To avoid misunderstanding, downvotes seem to happen not because community members recognize the duplicate account, but because of quite consistent low quality of the posts.
I wonder what happens when their duplicate account gets merged into the main one.
More specifically, does script kick in and starts undownvoting posts made from duplicate accounts on the false premise that some of community members have been previously "caught" serially downvoting another user account?
For the sake of clarity, here's more formalized issue description (discovered thanks to now deleted answer).
