I have to say that recently I see a lot of "legit" (likely no second accounts) entries in the top league4.
For me legit is likely: win rate up to 65%, games played 200+.
Dirk, Ataxius, lobotek, kajiKira, Tralalo, werfawf, Mehran mira is not new but now is very strong, rmg, technik freak, mattiacci, etc...
Aside from nullpointer (I will define a formula to count the "number of games passed before losing the top spot" while analyzing the db dump), johnbob and all the others that have 1000+ games (so, well known since alpha 5.x), those are all new. That's good it means that we have influx of new players while other go inactive. For example christian is not active anymore for the moment.
