Definetly! You can use SPARQL to query the database! Kinda new to the whole thing, but I think this at least shows how many benches you have edited as the last person.
SELECT ?user (COUNT(*) AS ?count) WHERE {
?bench osmt:amenity "bench";
osmm:user "Ludrol".
}
GROUP BY ?user
LIMIT 2
Which returns 60 :)
I ran this in Sophox :)
