The definition of "sneaky vandalism" from WP:VANDAL: ''Vandalism that is harder to spot. This can include adding plausible misinformation to articles, (e.g. minor alteration of dates), hiding vandalism (e.g. by making two bad edits and only reverting one), or reverting legitimate edits with the intent of hindering the improvement of pages. Some vandals even use edit summaries such as "rv vandalism" to mask their changes.''

"Jerk, Beefy!" is the very reason that the "sneaky vandalism" definition is included in WP:VANDAL. Some examples:
 * Keratoconus - added suggestion that obese people are more likely to be afflicted with keratoconus, citing article that does not contain any such statement.
 * Flowers for Algernon‎ - using an edit summary of "removed duplications", one duplicated statement was removed along with another, not duplicated statement. A possible error, but acknowledged as deliberate in this diatribe.
 * Crepuscular & Julian Barnes - repeatedly added "Crepuscular is the favourite word of novellist Julian Barnes". Also in Julian Barnes, added unsourced assertion that a novel was being simutaneaously published in Romanian, giving Bulgarian name of novel.
 * Cal Henderson - repeated addition of assertion that Cal Henderson is colourblind, with reference to a web page related to colour vision, but containing no indication that Henderson is colourblind.
 * Max Miller - unbelievable assertion that "For ceremonial occasions, Miller's [statue's] outstretched hand is adorned by a large boxing glove", with invalid (page not found) reference.
 * Rachel Robinson - asserts that "Author Judy Blume name-checks Rachel in her book Here's to You, Rachel Robinson", which is a book about a fictional teenage character named Rachel Robinson. Interestingly, the assertion in the Rachel Robinson article that it is actually about the real life Rachel Robinson was added by blocked user HappyUser (sockpuppet of blocked user Kitia), who seems to share "Jerk, Beefy!"'s interest in Judy Blume articles.
 * Dark Star (brewery) - addition of list of beers, including "Beefy Bitter", which is not listed on the Dark Star site. This was also added to the Evening Star (pub) article with the claim that it won an award for best ale.
 * Teletext - some plain old vandalism here
 * Don Black (white nationalist) - slightly cleverer vandalism here, added category "Black People"
 * for added fun, see Chris Parkinson a complete nonsense article, to which "Jerk, Beefy!" contributed the image. Note the overlap of articles edited by other contributors to Chris Parkinson.
