Gibberish from Shanty

Last week on the pier in Karamja I ran into a shifty person who names himself Shanty Claws. He informed me of the plight of some poor children who had been kidnapped and, being the good adventurer that I am, I proceeded to rescue then from their new "job" of fuelling a stove. What confused me though is the words that this Shanty used while talking to me. He offered a festive tree for my, in his words, "player owned house". I do not know this "player" he talks about and I can assure you that my house is my own! I do not rent it from anybody; why, I built it with my own two hands. Also he mentioned a member service I should be on. I think I'll go ask at the HAM what he is talking about as I cannot relate this to anything I have encountered as a citizen of Runescape. Maybe they started a new drive and are recruiting members for it?
