I don't think you need to worry.
When this item first appeared, I saw that it was a Locked item, which means that no-one can look at it. So it's somewhat pointless being there anyway, even is there is some unwelcome message/link locked away there?
Yes, the profile message can be looked at, but there's nothing much there either, apart from some self advertising.
I sent a message back then to the Forum's 'Contact Us' address, but no action yet?
Personally, I suspect that the 'Locked' item is more trouble than it's worth - I suspect that this item can be selected/activated by accident, and/or before the poster fully realises the implications of the Locking? Can it be removed?
