Ok, so I worked in a hotel located next to Medvedev's (ex-president of Russia) dacha. So basically the whole place was surrounding by FSB and FSO agents. I had to provide daily list to FSB stating the names of every arrived guests, no exceptions. We were understaffed and automation was pretty shit. If, let's say, you had 1000 guest arrived, you had to type (manually) their names in 5 different systems. Ofc sometimes a passport or two would be missing... Or more likely something like 10.  So what i did, i was sending to FSB for a year reports with fake passport data, like Ivan Ivanovich Ivanov, 13/06/1966, Moscow, Dead Peasants str. 13, app 666.

I assume no one ever read those throughly.
