It was a gimmick account intended to confuse people
Eh, Poe’s law is in effect. truther would absolutely use Rappler as a source if it helped his narrative. He also contradicted himself several times by not actually reading the article he was posting to attack Robredo or anyone associated with the opposition. So your satire may have actually been too accurate. truther is a dumbass and has no integrity after all.
EDIT: On another note, I just found out na mod na pala siya ng r/philippinesbad na subreddit. This is just more reason to dismiss that subreddit as nationalistic nonsense.
