Former England captain Rio Ferdinand "should have known better" than become involved in a Twitter row which has seen the QPR defender suspended for three matches, according to the English Football Association.
The 35-year-old (pictured) was handed a £25,000 fine as well as suspension for using the term "sket" - which is a term for a promiscuous girl or woman - on the social media site on September 1 following a message suggesting Ferdinand's team needed a new centre-half.
Ferdinand, who left Manchester United in the summer, has yet to confirm whether he will appeal, with the deadline set for November 10.
The veteran defender, who attended the Web Summit at the RDS yesterday, is a regular Twitter user, having sent more than 14,000 tweets since signing online in June 2010.
The FA's Independent Regulatory Commission on Monday released its written reasons for the case.
The statement read: "With nearly six million followers Mr Ferdinand is clearly an experienced Twitter user and he should know better than to respond in the way that he did.
"It is said on his behalf that he is one of the most high profile sportsmen on Twitter and he is, without doubt, a role model for many young people, no doubt throughout the world. His responsibility is therefore that much greater than many others.
"Unfortunately there is no formal or direct admission and there is certainly no sign of remorse."
Ferdinand was last month charged by the FA with "misconduct for a breach of FA Rule E3 in respect of the comment and it was alleged that such a comment was abusive and/or indecent and/or insulting and/or improper. Further it was alleged that the breach of Rule E3(1) is an "Aggravated Breach" as defined in Rule E3(2) as it included reference to gender".
