"Re: any posts to do with children, I would always just post their first name {or nickname or screen name} and the initial of their last name". -Sheherazad
I want to thank Guest Sheherazad above for her comment that I'm quoting. As a result of her comment, and my concerns re the fact that there are crazies on the Internet as well as elsewhere, I have edited the last names of 'informants' that were posted on my website www.cocojams.com, leaving only the first name {nickname or screen name}, and the initial of the last name. [I started with the pages that are primarily children's centered such as cheerleader rhymes, and insulting rhymes. And I intend to go through all of the pages of that website and remove the last names of adults also]. In addition, I removed the names of schools, and the grade level the child is in in that school. I also edited the "contact us" of that website to reflect this change. And I posted a notice of the policy of only using first names {or nickname or screen names with or without an initial of the last name}.
I should note that in the introduction to Shermans & Weisskopf's 1995 book "Greasy Grimey Gopher Guts: The Subversive Folklore of Childhood", the authors indicated that they use the first name and last initial of their informants because children were shy. When I edited those Cocojams web pages, I was surprised at the number of entries that I had of informants who had sent in their first name & last name. Maybe it's only the really confident child who would make the effort [easy as it is] to send in examples of rhymes and other materials. But I think it's more going on than that. I actually think that children/youth like to see their name in print.
Be that as it may, I believe removing last names from children centered pages {and from other pages as I will do} is the right decision.
