They also used a bunch of other fake names (Jigar Kumar, Dennis Ens) for the personas that put social pressure on the original maintainer. And the ifunc changes were done by one "Hans Jansen" who also later opened merge request to Debian. These are fairly eclectic names with no pattern, which was the point I guess. We don't know what level of misdirection is going on with the names, so "Jia Tan" is interesting but not particularly meaningful either way.
