One's like discussing soccer, make a lot of sense.
Have to love the replies that all go, "[winning team] had an (un)expected victory, the score was ____, the team should keep up their streak, but [losing team] did well/poorly so it was a well-earned victory/predictable"
A simple strategy that is no doubt employed by signature spammers is to create a sockpuppet account to frame simple or general questions in a new thread.
This creates a space of available replies considered sufficient substance (i.e. how can answering a Newbie's question be spam?) provided moderation isn't on a thread-wide level. I've seen more than a few examples of low-rank topic creators, and it would be straightforward to simply cycle through a set of basic topics. This is all before considering subsequent alts and of course the genuinely curious new users, who could also unknowingly perpetuate spam threads. Boards of interest include Lending, Scam Accusations, Investor-based games, and Beginners & Help - plenty of typical one-line responses about thread creation or generic tips (collateral, format, ponzi, simple answer respectively).
I wonder if deleted posts should have an additional merit or activity penalty.
