UPD: The calculation updated, for some reason I filtered only CF style competitions. Now it includes everything. Still ruban best :)
I revisited some data from Codeforces and, after 5 years, decided to calculate again who has participated in the most contests. I took into account all official contest participations, including those where a user participated unofficially. However, I excluded Practice/Virtual contests.
P.S: I think no one will beat ruban ever :)
