The Mueller report did find plenty of evidence of Russian interference, just not enough to charge Trump. It was a damn site better than the British report on the matter, though, which basically just said "we didn't find anything because we didn't look".

Cambridge Analytica absolutely had a role to play as well. The company was disbanded to try and prevent any fallback, however the same players are acting under different brands. Targeted Facebook ads have proven too effective, you can tell whatever lies you want if you select the right audience, then there will be no one to challenge them - particularly if you do it just before the election.

Based on your vernacular, it sounds like you're a hexbear user washed up on our shores and circumventing the defederation, shilling for Russia.
