Roskomnadzor has also worked to unmask and surveil people behind anti-government accounts and provided detailed information on critics’ online activities to security agencies, according to the documents. That has supplemented real-world actions, with those surveilled coming under attack for speaking out online.

The verb to surveil has apparently become an English word. It began as military jargon, derived from the French surveillance, meaning supervision or observation, which turned into the English word, surveillance. Etymonline.com says it started with the French Terror, when “‘surveillance committees’ were formed in every French municipality in March 1793 by order of the Convention to monitor the actions and movements of suspect persons, outsiders, and dissidents.”. It also says that “surveil” is probably a back-formation from surveillance, and dates it to 1903. It was primarily military jargon, I think, until the Paid Praters got ahold of it.
Be that as it may, it’s an ugly innovation and completely unnecessary, since we’ve already got to survey, as in “master of all he surveys”, a verb derived long before 1903 from the French verb surveiller, which is where surveillance came from in the first place. In ordinary English, we also used to say “keep under surveillance” or even “watch“. Oh well.
