Yes, but there is a difference between being curious and finding out whatever you can, and posting the results of that search to a public forum - especially when the word "secret" is in the contact email address. It just seems a little unnecessarily unkind.
I suspect it never really occured the grandfather - because there wasnt really any secrecy, this is a community that generally scoffs on secrecy as "a bit silly really" and there appeared to be no harm in spreading possibly interesting knowledge.
Not deliberately malicious I am sure.
I was going to post it too but checked myself at the last minute.
