The Swansea defender says the London side should be more concerned by the Hammers' "ugly football" rather than insult him on Twitter following the striker's red card
The striker was dismissed by referee Howard Webb during Saturday's game at Upton Park after being adjudged to have swung an arm into the face of the Spaniard.
The Football Association announced on Tuesday that West Ham's appeal had been turned down, and Flores posted a video of the incident on his Twitter page - insisting the intent from Carroll is obvious.
"I'm a bit tired of the strong insults from the west Ham fans. Whoever doesn't see the aggression in that action is blind," he wrote.
"They should be more preoccupied with the ugly way their team play football: always making very long passes and never quick short passing.
"They should be worried about that before caring about such evident things."
Carroll will now serve a three-match ban, missing West Ham's games against Aston Villa, Norwich and Southampton and, seemingly in response to the FA's ruling, posted "DISGRACEFUL!!!" on his Twitter page.
