That's not spam, that's a hint to all the other nobles to welcome the new person.
I agree with that. To hold new players is better that many realm mates welcome him/her in public. If not the new players see a desert place and won't come back again or individual messages tha maybe repeat the same things
I remember in Eston an year ago there was some players that did silly and annoying talks to the whole realm, nobody cares about but they did insist until they got annoyed too and quit...well they didn't seem discouraged by clicking twice. So in the end if someone want to spam he'll do anyway, if someone wants to send a regular messages maybe sometimes he's discouraged by the "go to Messages page...etc"
