"This Troper" spelled backwards. They've appeared in Her Code Name Was "Mary Sue", Purple Prose, and Meta Fiction, is the God of Examples, makes The Cameo among the Tropes Of Legend, and has been Killed Off for Real at the time of The Stinger for You Just Told Me. Basically, he (or she) is the TV Tropes Author Stand-In version of John or Jane Doe. Not to be confused with the Alien Hive Queen of the same name who hosts our page on The Galaxy's Greatest Comics, or the main character of TV Tropes The Webcomic (despite superficial similarities).
If you want to use two people, however, go with Alice and Bob.
Although, it might be taken for someone referring to "Report This" with "This" spelled backwards. Or "reports it," though that would make almost no sense at all. Or the word "Report" followed by a rather different four-letter word.note Or an order to report any Sith sighted. Or an order to report some turban-wearing guy from the Indian subcontinent (what for, we don't know. Nor do we know who to. But you should report him nonetheless!)
As a small note, few are aware that Report Siht was an illegitimate child. (S)He's fine with people knowing it, though. In fact, (s)he thinks it's magnificent. (S)He may or may not be related to Trope-tan. He or she has an Evil Twin called Report Taht and and a Cool Big Sis or bro named Report Rehto Eht.
As of late February 2020, they now go by the name "Gnitirw Nosrep-Tsrif", pronounced "nee-tee-roo nos-rep-tsruhf", but (s)he's fine on using the deadname for recognizability's sake.
