“Nobody is thought to be ignorant of the law”, or in US Law “Ignorantia juris non excusat”, “ignorance of the law does not excuse”.
In this case the law is the 1988 Malicious Communications Act, section1:

(i) a message which is indecent or grossly offensive
(ii) a threat or
(iii) information which is false and known or believed to be false by the sender or
(b) any article or electronic communication which is, in whole or part, of an indecent or grossly offensive nature,
is guilty of an offence if his purpose, or one of his purposes, in sending it is that it should, so far as falling within paragraph (a) or (b) above, cause distress or anxiety to the recipient or to any other person to whom he intends that it or its contents or nature should be communicated.
(2) A person is not guilty of an offence by virtue of subsection (1)(a)(ii) above if he shows
(a) that the threat was used to reinforce a demand made by him on reasonable grounds and
(b) that he believed, and had reasonable grounds for believing, that the use of the threat was a proper means of reinforcing the demand.
(2A) In this section ‘electronic communication’ includes _
(a) any oral or other communication by means of a telecommunication system(within the meaning of the Telecommunications Act 1984 (c12)); and
(b) any communication (however sent) that is in electronic form.

(4) A person guilty of an offence under this section shall be liable on summary conviction to imprisonment for a term not exceeding six months or to a fine not exceeding level 5 on the standard scale, or to both.
Liam Stacey made a number of comments on Twitter that were deemed to be offensive under the law. He can’t claim that he might not have known this law as that is no defense. He can’t say “Oh it was twitter”, because that is no defense. He can’t say it was PWI (Posting While Intoxicated) because voluntary drunkenness is no defense.
He was got bang to rights.
The plus out of all this is that we all know now what the law is and how it applies. Now no one has any excuse at all.
Abuse people online and you may face the consequences.
