English to Spanish Tech/Engineering Computers (general) current issues

Hey guys, I'm translating an article about how teenagers now tend to upload videos asking if they are pretty or not, and I found this : "digital vigilantism". I can't find a similar expression for that in spanish (I found "vigilantismo" but that word doesn't exist on spanish dictionaries). How would you translate it in this context?

"A YouTube search for “Am I Pretty?” turns up more than 23,000 results. Some of the videos date back to 2009, though most have apparently been made in the last year or two. And more are being uploaded (and taken down) every day. Lately, the phenomenon has spawned satires, spoofs, digital vigilantism and at least one piece of performance art".

Thank you in advance.
