I don’t want to mock people pretending they don’t have indoor toilets.
Sadly, it’s not really pretending. This article is from 2019, but the situation isn’t much different today:
More than one-fifth of Russian households do not have access to indoor plumbing, according to official statistics obtained by the RBC news website on Tuesday.
and
In rural Russia, almost two-thirds have no access to indoor toilets, 48.1 percent of whom use outhouses and 18.4 percent do not have a sewage system.




I probably should’ve quoted this part, as well:
I guess piping sewage into an open pit counts as a kind of system, and it’s definitely septic.
