Yes, of course, when counting votes, those who have never attended should meet the criterion: at least 1 year of registration on the forum.

Well, if the ability to choose multiple options is really needed, then Merlin's option would work, i.e., a person can distribute their total points between two cities, instead of giving a full vote to one and then another... This would give the person two votes.
And, as another option, someone already mentioned it, we shouldn't count the votes of local residents.
