The Drive-By Updater makes one, maybe two, edits and then disappears into the e-ther.
In many cases, this is a passing browser who spots an obvious mistake to fix. Also may exhibit the behavior of a Clueless Contributor
There is nothing inherently wrong
with Drive-By Updaters, but only if their contributions properly follow guidelines. Since most Drive-By Updaters don't bother to stick around to learn what those guidelines are, however, the practice can be less of a joy for the regular Tropers
After The Google Incident
anonymous edits were disabled, effectively making these contributors extinct on this wiki.
