I don't think you can get compensation if your case hasn't been heard and proven. It won't just be given to everyone who mentions it now.
The reason I'm a little less sceptical, is because i posted on here on a Jimmy Saville thread about how he had been a bit lecherous and creepy to me and my sister (early teens) at Stoke Mandeville hospital, before asking us to go with him to see his office. We didn't and i really hadn't thought about it since. It is only after everything else came out, that it even seemed relevant. It's just a personal confirmation - not an attempt at getting money.
