As for what we should do with questions coming from our "resident troll" on their own merits, all questions I’ve seen should be closed Off Topic (out of scope). Questions generally include a link to a page published on the Internet, an excerpt, and a proposed correction. The question is whether the excerpt should, as the OP thinks, be corrected or what the text would mean if corrected as proposed. The proposed correction is usually unnecessary. Sometimes there are multiple proposed corrections. Sometimes there is no link. Sometimes there is an indication that a general reference was consulted before asking.

Per the FAQ, literary criticism and critique requests are Off Topic (out of scope). Proofreading is also Off Topic (out of scope) unless the source of concern is clearly specified and unless the question is based on an actual problem that the OP faces.¹ Proofreading other peoples’ published works does not qualify, especially when there is no real problem.
Arguably there are more close reasons which apply on the merits. Too Localized (“the Internet is fine” is unlikely to help anyone, not even the poor OP). Exact Duplicate (when applicable). Not A Real Question when the question is unclear or incomplete (lacks context and prior research). The only close reason that applies less to the merits and more to the troll is Not Constructive.
Many of these questions are also cross posted without attribution to other non-SE fora such as EnglishForums.com, WordReference.com, and UsingEnglish.com, the BBC Learning English Message Board, and Yahoo! Answers. When this occurs, the question should also be flagged for moderator review, as that creates a legitimate concern about copyright.
