Samba made catastrophic errors in the opening 22 minutes to gift Fulham their first two goals in the west London derby and defeat leaves QPR seven points adrift of Premier League safety with seven matches left to play.
The 29-year-old subsequently apologised for his performance via Twitter and then received a number of replies from users, with several stating his performance did not justify his believed £100,000 per week pay packet.
However, one particular tweet made Samba snap. Feeling he had been the victim of racial abuse he launched into an x-rated tirade, which was soon deleted.
He later took to the social networking site again to explain his actions. “Just to say I am human and like any others words can be upsetting, the money comments and performance tweets I can deal with to a degree,” he tweeted, after previously telling his followers to “get over it [his wages] and support the team”.
“As for the racist abuse I receive last night I did not deserve at all.”
Samba moved to Premier League strugglers QPR from Anzhi Makhachkala in January for a fee thought to be £12.5m.
He had also experienced racism during his 11-month stint in Russia, most notably when a banana was thrown at him from the crowd during a match against Lokomotiv Moscow.
The Congo international threw the banana back into the stands, but was later forced to apologise for the incident after the Moscow club disputed that it had been thrown by one of their supporters.
Samba did vow though, to continue the fight against racism in the Russian game.
“I feel extremely passionately about racism in football and will never let the small community of racists break me,” the centre-back said, following the unsavoury incident in March 2012.
“I’m a strong character and will keep fighting for my team. Although I was of course angry at the racism incident, racist issues here are no different to what I have experienced in other countries.”
