The latter part at least is true. Sending "grossly offensive" messages is illegal under the Malicious Communications Act 1988 and the Communications Act 2003, specifically Section 127:

> a person is guilty of an offence if he—

> (a)sends by means of a public electronic communications network a message or other matter that is grossly offensive or of an indecent, obscene or menacing character; or

> (b)causes any such message or matter to be so sent.

I suspect the former is also true, but am not well-read in that area

[n4r9]

The full wording of the text is:

> A person is guilty of an offence if, for the purpose of causing annoyance, inconvenience or needless anxiety to another, he—

> [F1(a)sends by means of a public electronic communications network, a message that he knows to be false,]

> [F1(b)causes such a message to be sent; or]

> (c)persistently makes use of a public electronic communications network.
