Sapphixy is a Twitter user who has shown up in other rat kingers' past posts such as in Jake Alley's and David S. Gallant's. What they are most notorious for, is their vigorous defense of Benjanun Sriduangkaew, one of the few people on this forum with a body count.
Sapphixy, or Sean, is a 41 year old public health economist, making them one of the few in the rat king to actually have a job (though it doesn't stop him from ebegging). They started out on the web back in the mid-90's, with typical nerdy interests. He had severalblogs, nothing too notable or exceptional. That would change some time in 2010 when he realized he was trans because he liked femslash stories.
