It used to be the rule that only one letter of a name was allowed, and the rest either left off or masked by ****** (usually equal to the number of letters) when attached to any discussion that mentions extras. Many guys are still following this rule, but some are not. The sticky that established this rule (and also defined what "extras" were sufficient for PA credit) seems to have disappeared during the hiatus.
I've RTM'd a couple lately, and one got fixed. Another, still on the front page as I write, lists four full names. The OP got his PA, so evidently a mod looked at it but didn't make any changes to it.
