I used the word [Moderator Redacted - Dictionary Word] in advertising ie "Don't trust a [Moderator Redacted - Dictionary Word] with your accounts get a Professional". Now I am being sued for defamation by a competitor because they are named M S. This person has not advertised or made themselves known before now, and I have used this particular word in advertising previously. Can this go anywhere? It seems this is based on us definitely knowing of his existence and that he was close by, which we didn't. This firm doesn't even have a website and doesn't show in google searches. On the same day we were made aware of his existence by him rocking up to our business address, he was physically and verbally abusive, stole our business sign and attempted to cause damage to the sign, a young 3-year-old child playing and a dog when later made to return the sign. This has been documented to police and they attended the property and his premises the same day. They were unable to arrest M S due to his levels of intoxication at this time.
