I crossed swords with some arrogant prick who decided he had the right to censor my posts. He insisted that I take down a post to which I replied that he could stick his censorship where the sun don't shine!
A few days later I received a further message from him saying that he had researched my background and now knew that I worked for such and such a company in Luxembourg and that unless I took down the post to which he had objected, he would message my employer telling them what I had said on social media. I replied "go right ahead" but I omitted to mention that I had retired 7 years earlier!
Apparently he did contact them and was told to 'foxtrot oscar and mind his own business' by my former boss who was a jolly forthright chap!
