I don't think OP is shilling here, otherwise he wouldn't mention the withdrawal limit issue wich resulted in him losing all his winnings.
OP is not a shilling but has been forced to lose all the winning due to withdrawal issues on the site, most of the sites that offer such big bonuses and winning always have a withdrawal limit or conditions that are hard to be met which potentially results in the total loss on the players so I will advise before you play or deposit on any site make sure to have read the withdrawal terms and conditions.
