Pablo

Prolific level creator and Quark/Constructor whiz.
Contributed many levels to Marble Blast Platinum and PlatinumQuest. Was an early adopter of Quark and responsible for the conversions of many pre-MBP 1.00 levels.

Derided by many for his levels in PlatinumQuest, which are often regarded as beautiful aesthetically but clunky and unplayable gameplay-wise. His level Fault Line in particular became a meme, after hPerks commented in his beta feedback "If anyone picks this level in a gem hunt tournament I'll rip their dick off", and it was subsequently picked by Nock in the finals against him.
In the proboards era, was known for artificially racking up his forum post count with small insignificant posts, including his catchphrase "Welcome aboard!" which was his go-to welcome post for new members in introduction threads.
