Hi,
No, I certainly would not buy anything from a spammer like the one who posted those messages. Yes they are persistent, and certainly a pain!

Thanks very much for deleting the messages!

... especially such messages posted on a thread dedicated to the health of someone we all hope makes or presumably by now has made a full recovery. I certainly hope that he is helping Peter Jackson to get his air force off the ground! I take my hat off to both of them!
Regards,
David.
