I don't see nothing strange in OP's question. When I just joined Bitcointalk, I had similar questions why multiple users have same signatures and avatars. I thought they promote personal business, but then why multiple users are doing it. Then I thought it may be ref links in signature, so I checked - it's not.
I saw posts about signature campaigns, but I couldn't relate to this and thought WTF it is.
And who conducts these marriages ? The Signature Campaign Managers
They are priests of Bitcointalk
