  "Kompromat" (the Russian word for "compromising material") has been
efficiently used to harass Russian political and business elites since the days
of the USSR. Online crowdsourcing projects such as "RuCompromat" made it
possible to catalog and analyze kompromat using quantitative techniques --
namely, social network analysis. In this paper, we constructed a social network
of 11,000 Russian and foreign nationals affected by kompromat in Russia in 1991
-- 2020. The network has an excellent modular structure with 62 dense
communities. One community contains prominent American officials, politicians,
and entrepreneurs (including President Donald Trump) and appears to concern
Russia's controversial interference in the 2016 U.S. presidential elections.
Various network centrality measures identify seventeen most central kompromat
figures, with President Vladimir Putin solidly at the top. We further reveal
four types of communities dominated by entrepreneurs, politicians, bankers, and
law enforcement officials ("siloviks"), the latter disjointed from the first
three.
