Tripfag

The original pic showed up on /toy/ on 4chan, which is generally anonymous (excepting tripfags) so the likelihood of it even being the same original poster is likely nil.

However, tripcodes weren't popular. The people who posted on the imagechan believed that anonymity was its strongest value, and ridiculed the "tripfags" that attempted to use a real name in an anonymous society.

A year after Shii wrote his essay, forced anonymity had become widely accepted on the image board. Anyone deemed a tripfag was quickly shot down and mocked.
