Eric Flint's early work in porn?

Any Eric Flint fans among my Friends? I've just come across a pornographic SF novel from approximately the late 1980s, credited to one "Fred Sparkrock". The last name is semantically equivalent to Flint, and the first names each have four letters. It's not a slamdunk, but it is highly suggestive. Flint's first published work wasn't until 1993 (and nothing else until his first novel in 1997). A presumably starving writer might feel proud enough of having a book published at all to not hide his true name very securely.

Whoever wrote it is quite familiar with SF tropes, and even SF fandom, as evidenced by the repeated references to a character named Yngvi, who is clearly a louse. If any of you have read a bunch of Flint, and are interested in reading this to see if there are any typical markers of his style, I'd be happy to get you a copy.

I haven't finished reading it myself yet. It's certainly no great classic in either of its genres, but the mix is intriguing enough to keep me reading…

Targeted Advertising Considered Harmful

Among the recent spate of discussions about ad-blocking, I came across a reference to this paper from two years ago, which, while fairly dense going, seems both thorough and correct. Recommended to those who are interested in the topic, or in economics in general.
