It's just an amusing way for Spammers to pass the time and also form bonds a bit; I dunno how to explain it properly, except that in a sense, it's something folks around here do to express affection or otherwise reinforce bonds within the community. It's also really informal.

I find the same as Jorick honestly, this practice is far more common in member lounge groups and roleplayer's than in spam.

Spam tends to function as one big happy family (and then some outsiders they decided they hate/dislike for one reason or other), but not often do they go into specifics as to relations. You get the occasional marriage or adoption, but not at the same rate as the other places listed.

This would also present an infinite-loop, making you married to your smoking-hot great-great-grandma.Now, if you had a TARDIS...

Oh boy! We'll cause an infinite looping family relations paradox with the Wibbly Wobbly Timey Wimey stuff!!!
