In another displeasing domain [sic]: some softwares [sic] have been used to optimize the score of "tubulo" and "memo-psy" games. It was extremely hard for us to detect this and to distinguish bad players from good ones.
For this reason, we have decided to remove these two games definitively from KadoKado.
Repeat after me: "The client is in the hands of the enemy." There are YouTube videos of people using Flash debuggers to cheat at KadoKado games, so it's not at all clear to me where to draw the line between "this game is too easy to solve in real time" and "this game is vulnerable because it's running in the player's browser." I liked playing Tubulo a lot, and didn't feel that my solver ruined it for me. Probably because I didn't have a screen scraper, so it was a strategic decision whether to take the time entering the problem into my solver.
