"It was no joke. I can assure you."
Gulliver1, if you can assure me then I'll look into this further. As far as I'm aware, it was just an inappropriate joke.
If you have any evidence besides the comment made which caused this suspicion, please send it my way and I will be more than happy to investigate further.
However, at present, it's a wild accusation. I'm only letting the accusation stand because the other member you refer to brought this on themselves with their silly 'joke'.
Please, this doesn't need further discussion.
Gulliver1, email me if you need to.
