I got another email from the moderators over at the BT beta broadband forums.  This was in response to a post I made in which I referred to another posting which mentioned BT-Webwise- here is my posting (I removed a name, indicated by ***, and I think the post is obviously a little tongue-in-cheek):

Whoops, now you’ve done it, ****, you’ve mentioned it in your sig. Well, your post has lasted 15 minutes so far!

Well, after my reference to that which must not be mentioned in a previous posting, and which earned me the last ticking-off email, I tried a different tack, and used the word it to refer to something someone else had mentioned. This time I got my final warning

Your recent post titled: “Re: Useage cap” has been removed as it contravenes with the Forum Guidelines.
Discussions about Webwise (whether this product is mentioned directly or indirectly) are off-topic.

Since I don’t really want to enrage poor S*******e further, I redacted his/her name!
