"Fakten" means "facts" in German and the ending "-huberei" is used in that language to describe an action that is stubbornly, shortsightedly or exaggeratedly directed to one end.
Faktenhuberei describes a situation when a lot of information is being provided by a person or through the media, without this knowledge adding up to anything in particular. This information is factually correct, but its only purpose seems to be to display those facts, or self indulgence of the person who provides it. Even if the information is new the listeners or readers, its usefulness is questioned by them.
Example of use:
"Prof. Sonnenschein showcased a lot of knowledge during his lecture about German literature from the middle ages, but to me it all just seemed like Faktenhuberei".
