Well, that is part of the value of a community/open source project, is the fact you can experiment/test various ranking algorithms rather openly without the assumption of malice/rigging.
Tbh, I think the OP has the right idea [in general] but the wrong execution. [e.g. The jab at PH in the name, rebranding after the initial influx of traffic, no clear strategy for experimentation with ranking algorithms in a crowd/open sourced manner, private comments]
I'm curious how quick they'll note the issues and address them. I considered building something but I keep running into RL related time constraints/problems that make it impossible for me to commit time before Jan. xD
